Gabriel and his parents were really nice and welcoming. Though his parents only speak a few words English, the communication was perfect. They also lend us an umbrella because it was raining in Barcelona the whole day and we had not had any with us. They also were really nice with check in and check out because we arrived really early and our flight back was late.
The street in which the apartement lies is full of bars. There you get tapas/pinchos for 1€! The only negative thing is that it could get loud in the evening/night but we had no problem with that. You can also find really nice cafes in the near and the metro station is only a few minutes away.
Totally would recommend it!
