Very comfortable for two couples. View from the terrace is spectacular. Comfortable beds, air conditioning and black out shades...we slept well. Close to grocery, Palacio Real and other sightseeing, and lots of restaurants...easy to get a cab, rent a car or take the metro. We stayed for 9 days and explored the surrounding neighborhoods. Lots to do and see in Madrid. Homeclub was very responsive to our questions. Security guards in the building were quite helpful and friendly. If you want to use the gym/pool, you should ask ahead of time. We will recommend this apartment to all our friends and family.
