Carlota's flat is just perfect to stay in for the weekend or even longer, like I did. The neighbourhood has its own "ambientillo", how do I translate this, it is just something you feel - all the bars, all the people, the chats, the night life. The metro station is closer than you can imagine. And the room is very brightfull and realy realy nice. I had a lot of space in the wardrobe and few shelves for myself, even the kitchen space! Seriosuly - there's no better place to stay in Madrid. Highly recommended! :)
