The communication at Sonder was practically non-existent, and whatever little communication there was, was extremely late and therefore irrelevant. The Sonder app was the primary means of communication, but the app and its backend system were so buggy that registration and subsequent usage was impossible (and I work in high tech so I've seen my share of buggy apps and platforms). Time-sensitive messages sent to Sonder via the Airbnb messenger about check-in issues and nonoperational wifi were not answered for least 5.5 hours. This made any stay at this property extremely risky. If there were any expected issues (locked out, key card not working, plumbing leaks, defective wifi, etc.), there was no way to get timely help. Check-out directions were not communicated until 4 hrs(!) after the check-out time, despite my asking for them the night before. Furthermore, an early check-in by 1 hour at 3pm (normal check-in was 4pm) required a fee that was 25% of the daily price of stay. Sonder did say they had a higher-than-normal number of guests staying at the property that resulted in poor communication. However, as they would have known about upcoming guest check-ins, a well managed company would have made sure they would have sufficient staff to deal with the increased demand. I would not stay here again. It's simply too risky.
