We asked if we could have an early check-in, just after midnight due to a late flight into DCA. The host approved and we booked it. Once we arrived at the Airbnb, the access code provided didn't work and we could not get into the property. I tried contacting the host, called many times, texted, and left a voicemail. We waited for an hour on the street, in the cold, at midnight waiting for the host to reply. Ultimately we had to cancel and find alternate sleeping arrangements for my trip because the host was nowhere to be found. Finally the NEXT morning they responded. They told me it was their mistake and messed up the dates, but they never apologized for the inconvenience.
** Beware that this host can be unresponsive and inattentive if problems arise **
