The host sent me self-check in instructions for me to check in late in the evening. Upon arrival to the Airbnb I noticed that the host forgot to send me the key-box code. An honest mistake. It was 1am and after one hour and thirty minutes of trying to contact the host who had his phone turned off— I was forced to find a hotel. The host admitted he forgot to send the key-box code and I doubt this will happen again.
