We stood in this apartment Jun 18 - 23. Two words - amazing place.
We came around 10:30 pm and there was absolutely no problem with meeting at the place with Rocio.
The place is clean and comfortable.
Area is amazing. 3 minutes walk from the subway. Located in non-tourist part of Barcelona. In the evening while walking we enjoyed this part of the city, there are plenty of shops, pizza places, bakeries, vegetable&fruits shops and even some Mexican places.
The only minus, which I believe related to most of the parts of this city - around 5 am, trash was taken away by the workers and it was quite loud.

To sum up, it was an amazing experience and we did not regret even for a second that we rented this place.
