We loved this location. I stayed with one friend, so we each had a bedroom. Apartment is in a local neighborhood. Right around the corner there is a street with lots of tapas bars where we ate most nights for local flavor. The apartment itself is on a quiet street.
Very convenient to the metro - the nearest stop us Parallel, minutes from the apartment and easy to use the metro to get everywhere. At the Parallel station, you can also catch the funicular to Monjuic. We used the metro to get to all the sights.
The keyless entry is convenient. At the check in time, the codes appear on the app and you are all set. We had one issue with the lighting in the apartment and the host (which is a management t company, very professional) was extremely responsive and send someone over to fix it right away.
We loved Barcelona and the quaintness of this neighborhood.
I highly I recommend staying here. I would stay here again!
