Great apartment. Steps away from Atocha metro/train station on one side, and Retiro Park on the other — very convenient! Open and airy living room. Kitchen has everything you might need. A/C was a nice touch, though you can also just open the big windows at night for a pleasant breeze.
Perfect for a small family. We were traveling witha one-year-old baby and the host even provided a crib and changing table for us. And there were toys for him to play with!
