It was a very nice stay! The contact with Michel before and during the stay was good, he responds very quickly and helps you with tips you can do in Madrid.
Entering the apartment went smoothly, using the smart lock. Michel gave clear instructions. We had a nice experience in the apartment, everything we need was there. The location is good, there is a metro station nearby, allowing you to travel easily to another place. Overall, I recommend you this apartment for your stay in Madrid.
