Great host, Mar was very friendly and helpful. She gave us a lot of good hints regarding the city. Location is perfect, walking distance to all landmarks, and very close to Retiro Park and Museo Del Prado. Flat is spacious, 4 bedrooms, double bed in each, and 2 single beds in the biggest of them. One full bathroom, one shower room and 1 exrra toilet with 2 basins. Kitchen, with "survival kit" graciously prepared for us by Mar - coffee, tea, sugar, milk, some fruits and pastries! Clean and recently refurbished, with nice wall decorations. Wonderful :) Flat is in old building which has a charming old lift, loved it! Flat is literally surrounded by good restaurants, including one terrace bar and argentinian steak place. Just wonderful stay, and flat is so big that even up to 10 people can stay there, if there are 4 couples who would share the double beds. There's also couch in the living room which can be used by another person! Thank you Mar for wonderful stay in Madrid!
