I enjoyed my stay in Madrid - the location is great and I could to all parts of the city withing 15 minutes! Communication was great and the family are very friendly and helpful. I only met the son who was very helpful, courteous and respectful. The flat is VERY small but comfortable enough to sleep at night. It is very basic and a bit tired (the shower doors fell off every time I used it!), but it is very clean, and the bed is comfortable :). Being on the ground floor, at the back of a building, means it is pretty quiet - great for a city break! However I am not sure how much air you would get in the heat of summer. I felt very comfortable as a single woman staying here. I would definitely recommend it for those on a budget. If you want a view or something fancy or you are on a romantic break, maybe not.
