My week in Carlos's apartment was the best AirBnB experience ever. Carlos was excellent in terms of communication, check-in, preparing the apartment, and so on. He provided a few extras as a welcome gift, which you don't always see. The apartment was spotless and well-provided with dishes, pots, glasses, spices, coffee and tea and so on. He also provided an adapter and USB plugs in the bedroom. The location is as perfect as you'll find in Madrid, 10-15 minutes easy walk to all sites and attractions, and in a lively - but not noisy-area. I'll stay there again on my next trip to Madrid.
