Amazing location- probably the best location in Barcelona! Soundproof windows help block noise on the outside, but noise from inside the building hallway travels and when other tenants were loud you hear it inside the apartment. Earplugs came in handy at night! Very clean, except there is a bit of a musty odor in the bathroom and kitchen, probably because it is an older building with old pipes. However the hosts did their best to help by putting in odor absorbing air fresheners, which did help somewhat. The hosts were very responsive.
