Book this place NOW! The place itself is charming, in a small apartment building. It has plenty of windows for natural light & curtains/blinds for when you want to block it out. It's really close to a lot of important points of interest (Mercado de San Miguel, Plaza Mayor, Palacio Real), but still not on a major street, so you were able to sleep restfully. Lisi, my main contact, was a big help to us and arranged for transport from the airport. Comes with a washing machine, so that's a bonus that helped us pack less for the trip.
