Communication was really terrible. Every time we reached out to the host, it was a different person, who had no specific information to assist me. When we arrived at the airbnb, the door code did not work, the one that was sent via airbnb had expired. We had to download and use the private third party Sonder app to find the updated code. This was never communicated to us via airbnb.
When we requested a late check out, we were initially told it was accepted for the time we wanted and no additional charges. But then were messaged again by different people with confusing information and sent a bill for additional fees. Then we were texted that we needed to be out of the airbnb before our new approved checkout time. This was extremely stressful and disappointing way to end our stay.
The host requires you to make an account with their private business and download their third party app and then provided different information and attempted to charge additional fees via these methods. All communication should remain through airbnb. I do not recommend staying with Sonder.
