You’re staring at a map of Barcelona, and your eyes keep drifting toward the edge. That's where the AC Hotel Barcelona Forum sits. It is huge. It is modern. It is also, depending on who you ask, either a genius travel hack or "too far away." Honestly? Most people who visit Barcelona stick to the Gothic Quarter or Eixample like glue, but they end up paying double for a room the size of a shoebox.
Staying at the Forum is a different vibe entirely.
The hotel, a Marriott property, is located in the Sant Martí district, specifically the Diagonal Mar area. It’s right across from the CCIB (Centre de Convencions Internacional de Barcelona). Because of that, it has this reputation for being a "business-only" spot. Boring suits. Lanyards. Lukewarm coffee in conference rooms. But that’s a massive misconception. If you actually look at the layout of this place, it’s arguably one of the best urban resorts in the city, provided you know how to use it.
The Location "Problem" (That Isn't Really a Problem)
Let’s talk about the distance. You aren’t on Las Ramblas. You’re about 5 kilometers away from the city center. For some, that’s a dealbreaker. But here’s the thing: the L4 yellow metro line is right there at El Maresme | Fòrum.
In fifteen minutes, you’re at Urquinaona or Jaume I.
You’ve got the best of both worlds. You spend your day getting elbowed by tourists in the Boqueria Market, and then you retreat to a place where the streets are wide, the air smells like salt, and you can actually breathe. Plus, you are literally steps away from the Diagonal Mar shopping mall. If you forgot your swimsuit or need a Zara fix without the crowds of Passeig de Gràcia, it’s right there.
The beach is the real secret here. While everyone is fighting for a square inch of sand at Barceloneta, the Banys del Fòrum and Llevant Beach are much more chill. You can walk to the water in five minutes. It’s paved, it’s clean, and it feels like the "new" Barcelona that was built for the 1992 Olympics and the 2004 Universal Forum of Cultures.
Rooms, Views, and the AC Aesthetic
The AC Hotel Barcelona Forum doesn't do "Spanish rustic." Don't expect colorful tiles or wrought iron balconies. It is sleek. Very sleek. Think dark woods, crisp white linens, and floor-to-ceiling glass.
The views? Unreal.
If you get a high-floor room facing the Mediterranean, you’ll wake up to the sun rising over the water. It’s a total power move. On the other side, you see the sprawling urban geometry of Barcelona and the Torre Glòries in the distance. The rooms are surprisingly large for European standards. You actually have space to open a suitcase. AC Hotels are famous for their "no-nonsense" luxury—you won't find a thousand tiny decorative pillows you have to throw on the floor every night. It’s minimalist, but in a way that feels intentional rather than cheap.
The bathrooms usually feature those massive rainfall showerheads. It’s the kind of shower that makes you late for breakfast because you just don't want to get out.

The Rooftop Pool is the Hero
There is a pool on the 13th floor. It’s called The Suite Bar.
Most hotels in the city center have "plunge pools" that are basically glorified bathtubs. Not here. This is a legitimate rooftop deck with a view that rivals any of the high-end boutiques in the city. In the summer, the atmosphere is peak Barcelona. You’ve got people sipping gin and tonics—the AC signature drink—while the sun dips behind the mountains.
The wind can get a bit wild up there since you're so close to the coast. Sometimes they have to close the umbrellas so they don't end up in the sea. But on a calm day? There isn't a better spot to decompress.
Eating at the Forum vs. Eating Like a Local
Breakfast at the hotel is solid. They do the whole European spread: Iberico ham, Manchego cheese, those tiny croissants that you tell yourself you’ll only eat one of (and then eat four). They also have the "AC Lounge" for tapas and drinks.
But you shouldn't eat every meal there.
Walk five minutes toward the Poblenou neighborhood. This is where the real magic happens. Poblenou used to be the "Manchester of Catalonia" because of all the factories, but now it’s the tech hub and a foodie haven. Go to Rambla del Poblenou. It’s a pedestrian street lined with terraces.
Find a place like Els Pescadors for high-end seafood or just grab a bikini (the Catalan name for a ham and cheese toastie) at a local cafe. You’re getting an authentic experience that the people staying at the W Hotel or the Arts might miss because they never leave their "luxury bubble."
Why the CCIB Matters to You (Even If You're Not a Suit)
The hotel is physically connected to the convention center. This is important for two reasons.
- Avoid the Peaks: If there is a massive medical congress or a tech summit like MWC (Mobile World Congress), the prices at the AC Hotel Barcelona Forum will skyrocket. Or it will be fully booked. Always check the CCIB calendar before you book your trip. If there's nothing scheduled, you can often snag a four-star room for a three-star price.
- Infrastructure: Because it caters to high-level professionals, the Wi-Fi actually works. In some of the charming old hotels in the city center, the walls are three feet of stone and your signal dies the moment you close the door. Here, you can actually take a Zoom call or stream a movie without the "spinning wheel of death."
Logistics: Getting There and Getting Around
If you’re flying into El Prat (BCN), don’t bother with the metro unless you’re on a super tight budget. It takes forever because you have to change lines. A taxi or an Uber/Cabify will take about 20-25 minutes and cost roughly €30-€40 depending on traffic.
If you want to feel like a local, use the tram. The T4 tram line starts right near the hotel and takes you down through Vila Olímpica. It’s a smooth, quiet ride and gives you a great view of the modern architecture in the 22@ district.
A Quick Tip on Safety
Barcelona has a reputation for pickpockets, especially in the center. The area around the AC Hotel Barcelona Forum is generally much safer in that regard because it’s less crowded and doesn't have those narrow, dark alleys. However, the Forum plaza itself is huge and can feel a bit lonely late at night. It’s perfectly safe, but just be aware of your surroundings like you would in any big city.
Is It Right For You?
This isn't the place for the person who wants to walk out of the lobby and be hit in the face by history. You won't hear church bells or see grandpas playing dominoes in the square.

It is for the traveler who values space, modern amenities, and a killer view. It's for the person who doesn't mind a short commute in exchange for a peaceful night's sleep. It’s for the family who wants a pool that actually has room for kids to splash.
The AC Hotel Barcelona Forum is a polarizing choice, sure. But for those who "get it," it’s one of the most consistent stays in the city. You know exactly what you’re getting: Marriott reliability mixed with Catalan style.
Actionable Takeaways for Your Stay
- Check the High Floors: When you check in, specifically ask if there is a room available on floor 10 or higher. The difference in the "wow factor" of the view is massive compared to the lower floors.
- Sea View vs. City View: The sea view is more peaceful, but the city view is more interesting at night when all the lights are on. Personally? Go for the sea.
- The "Secret" Gym: They have a fitness center and a sauna. It’s rarely crowded because most guests are either at the beach or in meetings. It’s a great way to sweat out the tapas from the night before.
- Explore Poblenou: Don't just turn right toward the mall. Turn left and walk into the heart of Poblenou. It's the most underrated neighborhood in Barcelona.
- Download the Citymapper App: Google Maps is okay, but Citymapper is much better for navigating Barcelona's bus, metro, and tram systems, which you’ll be using a lot from this location.
- The AC Signature: Try the lavender sachet. AC Hotels usually have them by the bed or at the front desk to help you sleep. It’s a small touch, but it works.
If you are looking for a base that feels like a retreat rather than a tourist trap, this is it. Pack comfortable shoes—you'll still be doing plenty of walking—but rest easy knowing you've got one of the best views in the city waiting for you at the end of the day.
Next Steps for Your Trip:
- Verify the CCIB event schedule for your dates to ensure you aren't paying "congress prices."
- Book a "Sea View" room specifically if you want the sunrise experience.
- Map out the walking route from the hotel to Rambla del Poblenou for your first night's dinner.
