Great flat, just as described in the posting. Really great location in the heart of Malasana! Close to city center and public transportation - could easily walk to all points of interest.
NOTE: there is not AC. We stayed in Cesar's place in the middle of a 100 F degree week, which made cooling off and sleeping comfortably somewhat difficult. Even with the doors open to catch it a breeze, it was still fairly warm and the street noise is loud (especially late at night when are going home from bars). Something to be mindful of in the middle of the summer when it is very warm 24 hrs a day.
