The first night, we did not know that our key to the front of the building did not work, because the building manager left that door open throughout the day, meaning after a late night after a wedding party, we got back to the building with the front door closed and we were not able to get into the building. We actually had to walk around Madrid for an hour, trying to find a hotel with an open room. We were refunded the first night and told the lock would be fixed the next day. It was not. Instead, someone replaced my key with one that could work, but it required a special technique that we weren't properly trained up on, meaning the second night it took us 45 minutes to figure out how to open the door, again very late at night. We found ourselves then leaving events earlier to avoid issues getting in. On the third day someone finally came to fix the door lock, so it was clear that there was a genuine issue that the building was dealing with. Being a day late to fix a lock for someone who is renting your apartment for 4 nights is atrocious. Furthermore, I felt uncomfortable getting WA messages from the landlord asking things like "will you be home at 15:45?" when it was not necessary that I am present while the lock to the building, not the apartment, is being fixed. This was simultaneously being done while I was getting messaged about other things in the Airbnb app, so I opted to only respond within Airbnb. While we were refunded the first night, I don't think it compensates for multiple nights of not being able to get into the rooms we are paying for. Communication around check-in was also very bad. It was also clear that the landlords were disengaged.
