I cannot fault my stay here - the location, host and apartment itself are excellent. Pedro was very communicative before and during my stay, making sure I had a smooth journey from the airport to the apartment and providing several recommendations for sightseeing, restaurants, etc. he and his daughter were very kind and hospitable.
The location is great whether you are opting to get around on foot or by metro. The apartment is clean, comfortable and well-equipped. I would definitely stay here again if I returned to Madrid.
