I messaged the host 3 times over the month between me booking the space and my arrival date, but never received a response. The host said she never got a notification through the Airbnb app. I probably would have cancelled regardless (ended up with other accommodations), but the fact that I hadn't heard anything, and had a bicycle I needed to safely store while there, I was certainly apprehensive about showing up. Willing to assume the host never got any notifications, but not a good experience either.
