Very nice apartment for either a family or group of friends.
Location is allright, specially if you rent a bike! (wich i hardly recomend). Its not walking distance from the Gotico or the Paseig de gracia but its very close to the Sagrada Familia.
The apartment was clean, and has got everything one needs (towels, soap, kitchen stuff, tv, AC...). Not a luxury or design apartment, but perfect for the price.
The service is very nice, we were received by Mariana, very nice girl which helped with everything she could.

The only minus: check out is at 10pm. Too early... if your plan to go to Barcelona for night life (i recommend), then you should consider other places because it is really not cool geting home at 7pm, and being forced to leave at 10pm.
