We had a great stay at Sonder! The location couldn’t be better in Central Square, and check in and check out were really easy. I would recommend getting the app and using the mobile key when possible, because there were a couple times when our key code didn’t work, but we were able to solve it with the app. Would gladly stay there again!
And yes, as other reviews have noted, the rooms are small. There are a lot of places to hang out at Sonder (a restaurant AND a rooftop bar AND the lobby) but if you have a bunch of friends staying there, crashing in a room will be…cozy. That’s not usually why I get hotel rooms, so it really was not an issue for us, but heads up if you want a big room, you’re not getting one.
