This apartment is large and can sleep many people, including 2 1/2 baths. We stayed for 4 days and had a family re-union of sorts with 6 people and had plenty of space. Claudio was most responsive and met us at the apartment to check us in and gives us tips, even though we arrived after 11 at night!
Please be aware this apartment is in a residential building and they need to keep noise to a minimum. If you are coming to party, go somewhere else, but if you need a spacious, quiet and well located place in Barcelona, this is it. Very close to two Metro stops.
