Federico apartment it is wonderful, it is big than in the pictures and well equipped. I couldn't believe how quiet the apartment was even though it was in the middle of a busy neighbourhood. He was very patient with our check in, since we were late almost 2 hours and all the communication with him was really nice. Since we were in 4 we grab mostly taxis and it was easy every time to get one. His apartment make us fill like home, we had a great time over there. I will definitely stay there again when I am back to Madrid.
