Everything is as described, we found a nice appartement in the middle of Gracia.
Pubs, restaraunts, supermarket are very close and this part of Barcelona is really the best.
Apartment is really central, 5 min to Metro.
You have to accept some noice in the evenings but if you would join some pubs around, maybe you are also reason for some noise.
Stay in Garcia, stay in that apartment and enjoy!
