This stay was confirmed but I got no responses on Airbnb or Whatsapp from the host. I finally heard back after waiting outside for 45 minutes with my luggage, and got instructions on how to enter. There was a person there who was cleaning other units and she helped me figure out where the keys were. After hauling my luggage up 5 flights of stairs, I got into the apartment and it was a mess as if someone had just gotten out of bed.
After exhaustive travel, I decided to book another Airbnb (I was told this was not the first time this has happened). Airbnb did nothing to help compensate my expenses. The host responded to be about 3 hours after check out time offering a cab to pick me up to an upgraded apartment. By that time it was too late as I just wanted to settle in somewhere and booked another stay. I'm still pretty upset about this situation, and this should not be allowed to happen.
