Maria was super nice, she was replying very quickly, and was flexible with our check-in. The place was stylish, cosy, clean with everything we needed. The location was perfect, it was within 20 minutes of walking to all the major sights like Prado, Museo de Reina Sofia, Puerta del Sol, Plaza Mayor, Retiro Park, el Rastro flee market, Parque del Oeste with Templo de Debod and others.
I would highly reccommend Maria's flat to anybody.
