I had a lovely stay at Marisa's. The apartment is very well located, with Retiro park and museums a short walking distance away. There are many cafes and restaurants around; walking to my favorite at Chamberi took only a bit more than 10 min. So you can really walk everywhere from here. The room itself is tidy and spacious, with plenty of storage space to make even a longer stay comfortable. And the views of sunrise and sunset are just great! Marisa made me feel very much at home :)
