Virginie was a great host and always reachable as she lives just next door. The apartment is nice and clean and provides everything you might need.
One remark, there is no door for the bathroom so you should feel comfortable with your travel partner about this.
The location is close to the metro, although you can really walk from the place to all the sightseeing spots in Barcelona. It's a little loud at night but that's the case almost everywhere in this bustling city.
All in all a nice stay and definitely a recommendation.
