It was a very pleasant experience to stay at Alex's place. Alex is a very good host who really cared to make our stay as comfortable and enjoyable as possible. His house is no doubt best located to look around many of the tourist attractions in Madrid. We just walked to everywhere and could walk back home when my wife felt tired to get recharged. It has everything you need to live a few days in Madrid (kitchen, washing machine, etc) and we could shop close at supermarkets such as Carrefour Express and Dia. Lovely house. It was a 5 stars experience!
