Texted host 45 minutes prior to arrival and did not receive a response. Arrived at the town house at check in time and was unable to enter with the provided code. Called the host multiple times, all went straight to voice mail, so I left a message. Texted host again and still no response. Contacted Airbnb and they were not able to contact the host and or get me in to the unit. One and a half hours after check-in I booked a hotel. One hour and 45 minutes after check-in I received a message from the host apologizing and providing a master code to use. I never attempted to use this new code since I was already at the hotel.
