The apartment was great. It was convenient, well air conditioned and reasonably priced. There is a square in the Gracia district just 100 metres from the apartment where you can enjoy authentic tapas. There is a supermarket within 100 mteres also. The metro station Diagonal is about 450 metres away and gets you everywhere you wish to go in minutesl. For example, La Rambla is 2 minutes on the metro at Placa Catalunya. At first we were a little confused with where to exit "Diagonal" on our return journeys home, but quickly learned Diagonal/Plau Claris is the correct one (there are many exits).
There are three flights of stairs to get to the apartment so not so great for the elderly!
