The mattress was very uncomfortable, but Sonder apologized for this with a monetary apology. The apartment was very nice and I loved the hotel vibe I got from it. Their communication team is a little bit difficult because you’re speaking to a new member of the team each time. Also, I almost was unable to attend my reservation due to passport issues, and when I asked for a refund they would not accept, even if I was unable to get into the country that the Airbnb was in.
