A really well thought through service. The place is in a great location, bright. You are greeted with well conducted information, advise and other small benefits for a traveller in a new city. A worthy stay indeed.
It CAN be a little loud during the night as the window is facing the street, but if you get some sleeping earplugs with you, it causes no issues (i am particularly disturbed by street sounds, my partner had no issues with them).
We would definitely choose this place again when viting Barcelona the next time.
