We very much enjoyed our time in Barcelona, however we were disappointed with the apartment. The interior was unclean (dirty shower room, and dirty laundry under beds(!) and of a poor standard (broken furniture and of what wasn’t broken was of very poor quality).
The one saving grace for the apartment is its location. If you are looking for somewhere a little way out of the city Gracia is a great choice. Full of lovely bakeries (Le Besneta (vegan) on the same road as the apartment), bars and eateries (Capverd) and a lovely flower/ceramics shop 5 minute walk away (Casa Protea).
Park Güell and the Sagrada Familia is walking distance from the apartment and well worth the visit. The apartment is well served by the metro (Verdaguer / Joanic stops) for easy access across the city.
I would highly recommend Barcelona and Gracia but would not recommend this apartment - too expensive for what it is.
