I use air bnb quite often as I travel a lot for work.
Sonder is by far the worst company I have ever rented from.
They do not leave you alone, every five minutes I got an email from them asking if I had checked in, when I would be checking out, if I needed anything. All I needed was them to leave me alone.
Sonder also came by the property to check something out
They were going in and out of units on the floor. They were entering places when people were not home and they did not send out an email to let us know they would be doing that.
I dont feel very comfortable about that.
Definitely not staying with them ever again.
