Just up front: this isn't an individual renting out a room. It's a condominium renting out some of its unoccupied units. They'll require you to download a separate app and communicate with them through that app, rather than airbnb.
When I arrived to check in, the entry code I was given did not work. I contacted Sonder several times, and was repeatedly told that the code was correct. Eventually, on my third try, after sitting outside for over a half an hour, I got somebody to reset the door code, at which point the code finally started working.
Inside, all of the electrical outlets were stuffed with...plastic? I'm not sure. In any case, the only way we could use the coffee machine was by moving it from the kitchen to the living room, where there was a functioning outlet, and brewing our coffee on the floor in the living room. I informed Sonder of this, and they created a ticket to deal with the issue, and the next day told me that the issue had been resolved. But it had not been. The outlets were still jammed with...something or other. We had the coffee machine on the floor in the living room the whole time we were there.
