Our apartment was nice and clean. I downloaded the Sonder app as suggested by the company and it definitely made the check-in process easier. They sent the building code early in the day so we could pop in and store our luggage. We didn't have any issues with luggage storage on our day of check-in but on the day we checked out all of the lockers were full by 8am. I had checked availability the night before and only a few were open. I tried to chat with management through the app but it felt like they weren't understanding my concern.
Otherwise our stay was pleasant. It was fairly quiet aside from street noise. There was a very polite security guard there for most of the nights we were going in and out of the building. We needed a couple more towels and after a quick chat in the app someone brought them to the apartment door.
I would stay in another Sonder apartment and would recommend this stay for anyone looking for a nice, simple stay in chicago.
