Apartment is close to some of the major attractions like National Gallery and the Magic fountain. Also its close to a major metro and train station so that it is easy to commute to other parts of Barcelona or take the train to Montserrat.
The apartment is nice. Unfortunately no air-conditioning that makes sometimes hard to sleep when it's hot but there are fans that help quite a bit. More suited for two guests because even though the master bedroom is good, but the smaller bedroom is indeed small and significantly less comfortable.
