You can't beat the location! It's a couple of minutes walk from the Joanic Metro and minutes from all that you want to do. But even better, it's close to a great square with cafes, shade, and all the magic of the Gracia neigborhood. There are dozens of small neighborhood shops and tapas places you can walk to and the plaza of St Joan church is a gathering place every evening for families, young people, kids playing, dog walking and hours of people watching.
Also, the apartment is a decent size for Barcelona so you have space to be and relax.
