We stayed at Marta's place for 3 nights. What can I say that others haven't? The place was fantastic. Right in the heart of the city -- about a 10 min. walk to Plaza Mayor, maybe 15? to the Prado. Everything was flawless. The living room in particular was so comfortable and inviting. Two supermarkets (Lidl and Carrefours) a short walk from the flat to get your basics. Had an issue with the fridge and washer and they came and fixed them immediately whilst we were out. A great place for a family!
