Mario’s place was great. The room is beautiful and very spacious, with lots of natural light, and the common spaces were all neat, clean, and outfitted with whatever you might need. Mario was very easy to get in touch with and was very kind and helpful throughout my stay. Location-wise, the flat is on the same block as the Cuatro Caminos metro and a ten-minute walk from the Nuevos Ministerios metro and cercanías stations, so everything both within Madrid and in its outskirts is a quick ride away. There are also at least three grocery stores within a block, along with many restaurants, bars, cafés, etc., so it’s a great choice whether you prefer to cook for yourself or to go out for meals. I recommend the place both for people just in town for a short visit or for longer stays - I stayed for five weeks and thought it was a great fit.
