This is a spacious and clean apartment in a nice neighborhood. We had plenty of room for our family of 5. The neighborhood is quiet, though we did have a couple of loud groups going up or down the stairs in the night. It is located a convenient walk to many of the sites in Barcelona, though it maybe preferable to take a taxi or public transportation as it's about 30 minutes to Sagrada Familia, Gothic Quarter, etc.
The apartment had some basics (laundry detergent, dish soap and a sponge) but could have had a few more amenities given the rates they are charging. Otherwise, the stay was quite pleasant.
