CONSTRUCTION 24HOURS
First, the good things: The room does look surprisingly like the pictures, and when I arrived it was clean and very well stocked (my room even had a dishwasher!) The staff, especially in the chats, was super helpful and very accommodating. The location is good, and while the neighborhood is not super nice, I always felt safe thanks to the doorman and the codes for entering.
The construction, however, killed my stay. I was lucky in that I stayed in a room on the other side of the construction, but you can still definitely hear it. And it's definitely 24 hours, sometimes even on the weekends (I stayed for over three weeks, so it wasn't just a one-off thing). I was warned about the construction only a couple of days before checking in, and even then I was told it was not after hours. When I complained about the 24hours schedule, the hotel only said that it was a problem between the city and the construction company. If I had been aware of the construction being 24hours, I would not have booked in Sonder. A responsible host would at least try to have contacts with the construction company and call them when they're operating after-hours.
