Perfect location!!! Next to Sagrada Famiglia in pedestrian zone, 50m from metro station, easy reachable by metro from airport with one change - station Sagrada Familia.
The flat in old city house, rather oldish (I like this kind of student standard, however it couldnt be of everyone taste). The small sleeping room next to loud lift and without window with 2 beds was just impossible to use for any of 3 of us (grand mother- doughter- granddoughter), so one of 3 of us endend up on the kauch in the living room that was OK for 4 nights. Bathroom VERY small and shower only 70x70cm, so not for big people. If you are flexible and not more than 3 people all toghether (the 4th would be too much) this flat is a good and practical choice and we 3 recommend it.
