This is the perfect place to stay for anyone traveling alone. The apartment is 20 minutes walking from the museums, and 10 from the Atocha station. The room isn't big but more than enough for one person. It comes with a closet (with hangers), a full length mirror and a desk. There is a window with shutters that looks out onto an inner courtyard. Everything in the apartment is comfortable, spacious and very clean. The bathroom is clean and modern. The apartment is so large that it feels like you're staying there by yourself. I didn't meet Carmen, but her son Nacho was there and was incredibly helpful and nice, and speaks great english. He went above and beyond to help me out. There is also a super adorable kitten. I was sad I couldn't stay longer! Have already recommended this listing to my friends.
