I enjoyed staying with Maria, she was very welcoming and made me feel at home. The room is quiet and cozy, the shower is hot, and the towels are incredibly soft. Her house is a quick walk from the metro and she gave me great recommendations for nearby restaurants. The bathroom is right next to the bedroom, so you don't disturb anyone on your way to use it, and you can make the room completely dark if you need to sleep in. Perfect for both the weary traveler, and someone who wants to be close the center of Madrid, but have a quiet place to return to.
