Our stay was really nice, the apartment is well decorated, cosy and comfortable, with all the needed amenities.
Xavier was very helpful, he gave useful tips about Barcelona and good places where to eat. He's definitely a kind guy.
The apartment can be a bit noisy at times because it's facing the main road, but it's well connected, it's only a 5 minutes walk to the metro and a 15 minutes walk to la Rambla.
