The apartment was simply perfect. Silent, modern and with everything we needed, exactly like he photos. It is on the 3 floor and has no elevator but the stair are spacious and it was not a issue for us (we were with 2 elderly people). The location was awesome just few meters from Opera and Puerta del Sol with lots of restaurants and cafeterias nearby. Luis was super helpful and kindly, receiving us with a bottle of wine and also helped us with the luggage on the arrival. I had a lot of queries during the stay and he was always prompt to help. I would definitely recommend it and for sure we would stay there again when we come back to Madrid. Thank you Luis!
