You’ve likely seen it sitting there right at the corner of Mayfair Road and Watertown Plank Road. The Sonesta Milwaukee West Wauwatosa at 10499 West Innovation Drive has been a staple for anyone visiting the Milwaukee Regional Medical Center or heading to a Brewers game at American Family Field. But if you’re planning a stay, you need to know that things are shifting—fast.
Honestly, the "business as usual" vibe at this location is undergoing a massive identity crisis. As of early 2026, the building is in the middle of a $23 million transition. While it has spent years as a 198-room hotel, the city recently approved a permit to turn the whole thing into the Waterfair Apartments.
What’s actually happening at 10499 West Innovation Drive?
The hotel has traditionally been the go-to for people who didn't want to deal with downtown Milwaukee traffic but wanted to be close to the action. It’s basically two miles from the Milwaukee County Zoo. If you’ve ever stayed there, you know the layout: eight floors, a decent indoor pool, and that signature "Innovation" restaurant that mostly served dinner.
But here’s the kicker. Recent reviews from late 2025 were... well, they were a mixed bag. Some guests loved the proximity to Froedtert Hospital (it’s a literal 5-minute drive), while others complained about "aging" carpets and a hot tub that seemed to be permanently out of commission. The hotel management even admitted in some public responses that capital for repairs was tight because of the upcoming conversion.
The plan is to flip the 126,000-square-foot building into 146 apartments. They’re aiming for "workforce housing," which is just a fancy way of saying rents that won't make your eyes water—specifically targeting the 20,000+ employees and students at the nearby medical hub.

Is it still a hotel right now?
It’s complicated. Construction was slated to start in January 2026, with a finish line of June 2026. If you're looking for a room today, you might find the "Sonesta" signage still up, but the inventory is dwindling as they gut floors to make room for kitchens and studio layouts.
Quick Stats on the Property:
- Built: 2008 (originally a Crowne Plaza)
- Rooms: 198 (becoming 146 apartments)
- The "Sea of Concrete": Developers are calling the massive parking lot "underutilized," so expect more buildings to pop up in that lot eventually.
Sonesta Milwaukee West Wauwatosa: The location's real value
Even if the beds are being replaced by sofas, the location at West Innovation Drive remains prime real estate. Wauwatosa—or "Tosa" to the locals—is basically the cool older sibling of Milwaukee.
You've got the Mayfair Mall just 1.3 miles north. If you’ve never been, it’s one of the largest in Wisconsin. Then there’s "The Village," which is the historic heart of Wauwatosa. It’s got that European feel with local spots like Blue's Egg (get the stuffed hashbrowns, seriously) and Cranky Al’s for doughnuts.

Why people used to flock here
For years, this Sonesta was the "smart" choice. Why?
- The Shuttle: They ran a free 3-mile radius shuttle. This was a lifesaver for people visiting patients at the Medical College of Wisconsin.
- The Space: With 16 meeting rooms and a 5,000-square-foot ballroom, it was a wedding and corporate training factory.
- The Price: Usually, you could snag a room for around $130–$160, while downtown hotels were pushing $250.
But let’s be real. The "Innovation" restaurant on-site was often closed on Sundays and Mondays, which caught a lot of travelers off guard. If you’re in the area now and the hotel kitchen is dark, just walk or drive a few blocks. Mo’s Irish Pub is right nearby for a burger, or you can head to Ally’s Powerhouse Cafe for a much better vibe.
The Elephant in the Room: The "Waterfair" Shift
The move from hotel to apartments at 10499 West Innovation Drive tells you everything you need to know about the current economy in Wauwatosa. We don't need more half-empty hotel ballrooms; we need places for nurses and researchers to live.
The developers, Samapa Development and Oakbrook Management, are keeping the outside looking mostly the same. They’re just modernizing the insides. If you were a fan of the indoor pool, there’s some good news—the plan includes keeping some of those "hospitality" amenities for the new residents. Imagine having a hotel-sized indoor pool in your apartment building. Not a bad deal for $975 a month.

What most people get wrong about this spot
People often think this area is just a boring business park. It's not. The Milwaukee County Research Park is actually quite pretty if you hit the bike trails. The Menomonee River Parkway is right there, and it’s one of the best places in the county for a run or a bike ride.
Also, don't confuse this with the Sonesta Select Milwaukee Brookfield. That’s a different property about six miles away. If you book the wrong one, you’re going to be very annoyed when you realize you're in Brookfield instead of Wauwatosa.
Moving Forward: Actionable Advice
If you were planning to stay at the Sonesta Milwaukee West Wauwatosa on West Innovation Drive, here is your checklist:
- Check the Status: Verify on the official Sonesta website if they are still taking reservations for your dates. With the conversion in full swing, many booking sites might show "no availability."
- Look at Alternatives: If they are full or closed, the Radisson Hotel Milwaukee West is right across the street and offers a similar vibe.
- Medical Visitors: If you are coming for the hospital, ask the medical center about "patient family rates" at the nearby SpringHill Suites or Residence Inn. They are often cheaper than the public rate.
- Future Renters: Keep an eye on the name "Waterfair Apartments." If you work in the Research Park, these units will likely fill up the second they hit the market in June 2026.
The era of the Sonesta as a traditional hotel at this specific address is winding down. It’s a bit bittersweet for those who used it as a home base for years, but that's Tosa for you—always evolving.
