Rafael's place is one station away from the airport, from there it takes about half an hour / 40 min. by metro to see the city's main sites. The place is situated in a calm neighbourhood, which also has some smaller shops and restaurants.
The one-bed room I stayed in was small but clean and practical for a short stay and had everything it needed. Kitchen, living room and bathroom can be used and are shared with other guests.
Overall I recommend Raphael's place and would book it again.
