The department is just the perfect place for a tourist in Barcelona! Very nice and quiet building, good beds to regain your strength after walking around the city, cosy living, equipped kitchen and everything very clean.
Instead of praising the place (we found it just as it was described) i'd better dissipate some concerns that i had myself before arriving: not so far away from the airport (around 35 euros in taxi), very close to the touristic places and to the local public transportation, we had no problem in coming back home at any hour, nice neighbourhood (as a recommendation of drinking one more glass before going to bed, definitely la Bodegueta de Verdaguer!), a mini-market just downstairs and of course, very nice hosts!
So stop worrying about your accommodation and start planning your trip! Enjoy Barcelona!
