We highly recommend this apartment. Mariana was a wonderful host. Due to our luggage being lost, she assisted us in securing the building owner to accept our luggage if the airline delivered it. Whenever we had a question on the workings of the apartment, she answered it immediately. The apartment was well-equipped. The air-conditioning worked very well, which was a necessity given the Madrid heat. The apartment was in a perfect location walking distance from the major sites, the train station and numerous excellent restaurants. Overall, this apartment rates as one of our best rental experiences.
