Cinthia is an excellent host. She is very welcoming, makes great effort to communicate in English if you don't speak spanish and to make you feel comfortable, and she provides good advice if you want to eat outside or look for a place to live in Madrid. Her appartment is clean and well furnished, and she respects your privacy in your room. Also a very nice person to talk to, very open-minded. Cinthia was a great host for me, arriving in Madrid for the first time with no understanding of the spanish language. The location is outside the center but near the metro line 3 so not an issue.
