Location, location, location. There are small streets and plazas everywhere with kids playing futbol while their parents sit in a cafe near them. There are places to buy cheese (can luc is amazing) and wine (wine palace) and bread so having happy hour at home is easy. We could use English to buy things.
To go on the small streets and have coffee or was fun to use a little Spanish as this area feels more local.
We walked to Sagrada Familia, Gaudi houses, Park Guell, toma ya (yum) for food and were able to get water and crackers at a market (convenience store) across the street.
We absolutely loved this area, having two baths and a washing machine. The second bedroom came in handy to sleep apart during jet lag.
The apartment was clean and the kitchen was huge and had everything we needed. We would only stay here if we returned to Barcelona (we also spent three nights in Poblenau but that area and the beach you can metro to), stay in Gracia.
