I made choice for Josep apartment to try Gracia. And it was a very good way for me. I find this distict smooth, no noisy but in the center of the city.
So I decide to looking for long term rent in Barcelona in Gracia instead Saria.
Thank for Josep to help me to make this choice!
Apartment is so well - you can stay here, work here and see in windows for relax.
Strongly recommend!
