We stayed for three nights as a party of nine adults and kids in total. Thx flat was in a great location, we were able to walk pretty much everywhere (apart from Parc Guell which is worth the visit , get tickets in advance). The flat was perfect for us, lots of rooms, great lounge, and the roof terrace was really welcome as the weather was so lovely. We bought pastries from the cafe downstairs each morning. We didn't use the kitchen much, certainly not for cooking meals, but the fridge was large and the cupboards seemed well equipped. There were two bathrooms which was fine for us, but may have not been enough if there had been 16 of us. It was a really easy journey there from the airport, we hopped on the Aerobus which stopped just round the corner outside the university. Check in was really straightforward. All in all, a great base from which to explore this fabulous city. I would definitely recommend this flat to large groups, whether families or not.
