Antonio's apartment is a true gem! If you're visiting Madrid, you must stay here. Antonio's apartment is perfectly located - it's within walking distance from the La Latina metro stop, Plaza Mayor, Mercado de San Miguel, Gran Via, Puerta del Sol and many other Madrid must see sites. (Be sure to go on a "tapas crawl" in La Latina - some of our favourite tapas were enjoyed here). The apartment is gorgeous, immaculately clean and was larger in person than what I thought it would be based on the photos. I'm a light sleeper and had no issue sleeping on the pull out sofa in the living room (which is spacious for two people). We really appreciated having a large shower (always with hot water!), AC and a hairdryer.
Antonio was a wonderful host - he replied to all of my emails immediately and provided pages of sites, restaurants, shopping, etc. we should visit while in Madrid. He also gave detailed instructions on how to get from the airport or train station to his apartment and kindly arranged for a taxi to pick up at 5:30am to take us to the airport.
I hope his apartment is available the next time I'm in Madrid as I can't imagine finding a better place to stay!
