This place is definitely in an amazing location. I found that many of the main attractions in Madrid were in walking distance: places such as Mercado San Miguel, and la Plaza Mayor, as well as Teatro Calderon. It was very secure since you had to go through two locked doors before getting to Antonio's place. While there was some tagging on the walls in this area and it gives the impression that it is an unsafe area, it is not. The air conditioning in the place worked exceptionally well, which was so appreciated during the hot summer temperatures that Madrid greets its visitors with. The place was very clean and just spacious enough for 4 people. Compared to other places in Europe which tend to have very small spaces such as shower areas, this was definitely spacious. Communication with Antonio was great. I would stay there again.
