Great flat!
My girlfriend and I had a great time at Nico's place.
We would definitely go back when in Barcelona next time.
The place is exactly as described, in a cool neighbourhood, with metro station nearby, and many great tapas bars in the area.
Having a supermarket right in front is another plus.
Also, Nico was super friendly and told us about the new years event at nearby Plaza Espana, which was a lot of fun!
