I spent a night in Ana's apartment and she is a really nice person.
The check in is very smooth (actually she waited for me, as I had some troubles to reach the place).
This place is quite far from metro station, about 15-20min on foot, but it is still a nice area with shops and food places nearby.
The room is quite cold (as many apartments in Spain), but it had a little heater provided, so it's not a con.
Recommed for that price.
