You will need a code for a phone app to unlock the door. The host did not meet us at check in, and sent the code literally at the last minute as we were standing in front of the door. And anyone in your party who wants to be able to open the door must separately set up the app on their phone. Guests not familiar with apps or language issues may have difficulty managing and coordinating things with the host. Otherwise, this was a great place. And the neighbors appeared friendly and helpful.
