The location is great and Karla is very accomodating. There are two small grocery stores just,below the apartment, convenient to get groceries. The Diagonal metro is a two minute walk. The Pedrera is also within walking distance. Quick ways to find the apatment location your first time: If you see the Obelisk in the center of the intersection of Passeig de Gracia & Diagonal, keep on Passeig de Gracia going slightly uphill (i mean don't go downhill). If necessary, look for Hotel Casa Fuster, its a large, very beautiful hotel. The apartment is almost across from the hotel, up the street about a 30 second walk.
