Our family had a wonderful 5 days in the lovely apartment .. it was very convenient for us to walk to the Diagonal Metro and get around Barcelona. There are also many nice restaurants and cafes nearby, due to lack of time, we could only sample La Peppita, the Thai restaurant and the Bagel cafe .. all just a stone's throw away. Also it was very convenient for us because there were several super-markets nearby for us to buy basic food items and drinks.
And of course, Joaquim the host was very responsive to our queries and requests. Our family would certainly come back again to the apartment if we came back to visit Barcelona in the future.
