I’m sorry that I have to give a negative assessment because the host's behavior was very unprofessional.
Upon arrival we found out we couldn't open the front door of the building where we were renting an apartment! The key fob to open the front door didn’t work. We immediately reported this to the host and he assured us that he was working on a solution to the problem.
Over the next two days, we reported this problem multiple times, asking for a working fob or a door code. Coming back from walking around London we couldn't get to the apartment which was very frustrating. The host always replied that his team was working on solving the problem and that we were to ask other residents to open the front door for us! First, it was uncomfortable for us. Second, the proposal expressed disrespect for the other residents of the building. Returning late in the evening, we were also to call other residents and disturb their peace?
After the intervention of the Airbnb Help Center that we learned that the host has no way to fix this issue during our stay. We finished our stay in a rented apartment for the first time ahead of schedule. Thanks to Airbnb's help, we found another apartment.
