Super location - Gracia neighborhood is great ( surprised us a lot ) with great bars, restaurants and the Gaudi works all around.
The apartment is a bit small but functional, with a good quality mattress / bed. Although a bit of restoration could improve it as not everything is top notch.
Terrace is big and great for sitting outside in end of May temperature.
For us it was good for our 5 days city trip and plans to stay out most of the time.
