Carlos is terrific. He goes far and beyond what is expected. He is extremely well organized, and the most helpful host I have yet encountered with Air BnB. The apartment we stayed in was very centrally located, quiet, well equipped and easy walking distance to the fantastic Madrid subway. It was perfectly clean, well equipped with a hairdryer and coffee maker with coffee and cool water in the refrigerator. The bed was comfortable and the bathroom well equipped with hot water and basic necessities. The building was safe and very near restaurants, cafes, the theater, and even a Lidl a short distance away. Carlos' place gets 5 stars on every front. I highly recommend staying with Carlos. Plus, he is such a terrific person.....so very helpful and nice.
