We had a great stay in Barcelona! the appartement has enough space for a family of four persons and is really nicely furnished. Very good location, erverything you need (supermarket, bakery, restaurants) is near by and even some of the attractions are in walking distance, otherwise there is a bus stop or metrostation around the corner.
The only thing to consider is the noiselevel as you are in a really busy district - anyway, we didn´t bother and I can truly recommend this place!
