This is such a good location. Barcelona is a place for walking and the grid system and excellent pedestrian crossings mean you get confident to just go off and enjoy. You can get to alot in a 15 minute walk from the appartment and to come back that distance is only 5€ if you are tired. There is food everywhere at every budget though the flat is a calm space just to chill out and make a meal if you want. Highly recommended.
