Antonio was extremely accommodating. We had originally booked a top floor apartment and he offered to change us to the first floor, as I was traveling with my parents and it was easier because of the stairs. He did this without hesitation, and it ended up being the best option. The apartment is beautiful, modern, clean, and comfortable, as well as amazingly located. When we were there, it was extremely hot in Madrid— yet being in the apartment was so nice and comfortable because of the AC. It made our stay in Madrid very pleasant. Would definitely recommend and stay again.
