Best thing about the apartment is the location! About a 15 - 20 mins walk to the beach and near many top attractions (picasso museum, la boqueria...). The apartment is exactly how it looks on the pictures so no surprises. Clean with towels / soap provided. Both the private sitting area and bedroom are on the mezzanine level. Not much lighting as it's the mezzanine. Since the guest bedroom is located on top of the owners bedroom, you have to be mindful of the noise. So if you don't want to bother tiptoeing around then maybe consider another place. We happened to wake up Concha up while we were packing ...quietly we thought...and she didn't respond well to it.
Honestly, this is the only issue I had and..overall the stay was pleasant.
