Excellent hosts. Juan (Natali's brother) made us feel very comfortable and himself cleaned the entire flat for us letting us do an early checkin.
The flat is small but very nice if you are a couple. For four people it felt a bit tight, but still for us it was enough.
The area of location is very central. hundreds of shops at 5 minutes away maximum. Loads of buses and also the underground is 5 minutes walk.
