The amenities, room, staff were excellent. Location is fine, only 10 minutes from downtown on foot - the neighbourhood itself is quiet but has stores. Checking in and out was smooth. Luggage storage was very helpful. Why poor? Our bedroom backed onto the neighbours' living room. At midnight: they watched Rocky, and sang along. They rang their friends, and described the weather. They banged every cupboard door, dropped everything on the floor, and generally did their best to keep us awake till pass midnight. Security went up 5 times to ask them to quiet down. Sonder rang them. The manager spoke to them. They still did it again. Since we were in Philadelphia for a conference beginning at 8am, this was not ideal. Sonder provides a noise machine and earplugs but it still wasn't enough (I may as well have been watching the TV with them). I think if you are going to separate rooms with a thin dry wall, then you need to be really explicit to guests about quiet time(s).
