BE REAL CAREFUL WITH THIS PLACE IF CHECKING OUT EARLY.
First of let me just say the apartment itself is really lovely and looks much better than on the pictures. No complaints there.
The issue for us is that we had to check out really early (6 am) because we were getting a bus to Lisbon. I asked the host how to proceed and she informed me to just leave the keys in the apartment and slam the door. We did that, however when we took the elevator down to the hallway we found to our surprise that the door leading to the street was locked with a key (all other days it could be opened from the inside without a key). We tried to get back into the apartment which wasn't possible as we already slammed the door. I tried getting in touch with the host multiple times but got no response at all. In the end we had to go door to door waking up neighbors until we found one who would lend us a key to the hallway (they were not happy). We finally got out but had at this point in time wasted a full hour and thus missed our bus and had to book a train instead. Not a fun experience!
