Toilet wouldn't flush for days, Sonder made multiple attempts that did not resolve the issue whatsoever. Once they got bored of trying to solve my issues, all communication stopped, forcing me to refund my stay via AirBnB (thank goodness they were involved).
On top of all that, they wanted to charge me to have some extra check out time despite the fact that I was fleeing a unit without a functioning toilet for days last minute. Customer service was a front, maybe if your unit is perfect you will be ok but you do not want to find yourself in need of Sonder's support. They will leave you out to dry, and I suggest you save some headache and do the same to them.
