We stayed here for one week, in the April and the place was very convenient for our sight-seeing visit to Barcelona.
A decent supermarket is just 100m away in one direction, the metro station is 200m in the other. And if you pass the metro, there’s an another supermarket and a nice bakery.
Sants railway station also not far away.
The place is excellent and I highly recommend it.

The only unexpected thing for me was to discover that bathroom actually doesn't have a door, only a doorway. You can see this doorway on the photos, but I just didn`t got that it is doorway to the bathroom. So it can be slightly cold to stand here after shower.
