If this location is available during your stay in Barcelona, book it! It's in the perfect location in La Rambla with so many shops and attractions in walking distance. The location feels super safe and entrance into the building was secure which was important to me as a solo, female traveller. The place itself felt very cozy and bohemian and was very clean.
I would say if you're looking for a quiet place in Barcelona, this might not be the best choice. La Rambla is loud and boisterous in the best way and you can hear all the fun going down on the street but with earplugs, you can easily drown it out at night.
My only regret is I only stayed for one night. I wish I could have stayed longer!
