We had a really great experience at Javier's apartment. He met us at the building's front door right on time and kindly showed us around the spacious apartment and beautiful private rooftop terrace. He even gave us lists of nearby restaurants and flamenco halls. Javier doesn't speak too much English but we managed to understand each other all the same. The apartment is not quite as close to the center of town as some hostels, but it's still only a 20-minute walk to the cathedral and the area seemed fairly safe. A couple of practical notes: The fold-out couch is a full-size bed (not just a twin) and the apartment has a washing machine but non dryer. Would definitely come back here!
