If you don't mind lots of stairs, and don't have a fear of heights, Gala's apartment will reward you with its stunning terrace.
It's not big, just enough for living. However the neighborhood is my favorite in Barcelona- dense, walkable and authentic. The main street to the south is closed to cars on weekends, and I enjoyed it more than any other place in the city.
On this street is a fabulous bakery, meat/cheese shop, local greengrocer, and just around the corner is my favorite churro stand. Within a few blocks are numerous cafes, restaurants, vermuterias, etc.
Please respect the neighbors- the city gets a lot of disrespectful tourists and the lovely people don't deserve it, especially this hidden gem of a neighborhood.
