Our stay at Carlos’s place was an oasis in the middle of a very uncomfortable situation with our flight cancellation. Carlos place is very close to the airport, only a few mins by metro and then 4 mins walking. He let us check-in much earlier than usual check-ins and also lent us his phone charger since our bags were at the airport. He was very friendly and accommodating...made every effort to give us a very comfortable and quiet sleep. The room is very clean, spacious, and the bed is the most comfortable one we have stayed in Madrid. If needed, would definitely stay at his place again. Highly recommended.
