We have just returned from a 4 day stay at this amazing apartment. As a family of four; 2 adults and 2 children age 9 & 6, it had everything we needed.
It is in a great located and we found it easy to find our way around on the Metro. Restaurants and bars are within a 10 minute walk from the apartment and the beach is about 20 minutes away.
We would definitely stay again when we visit Barcelona.
