We really enjoyed our stay in Madrid at Casa Marilyn Monroe! It was the perfect place for us, our children and their friends. The beds were fine and really soft, the showers were great and there was more than enough closet space. The livingroom was cosy and comfortable and the dining space was surely big enough for the eight of us. In the heat the fans and airco were very necessary. The masterbedroom cooled off easily, but the other bedrooms were rather hot, even with the fan.
The area around the apartement was really nice, especially the park El Retiro. It's an amazing park to take a walk during the hottest moments of the day. The public transport was right in front of the apartment and well organized.
