The apartment is as advertised - plenty of space, I would say for a family of 5 it would be ideal. The location is 25 minutes walk, or 3 subway stops, from Pl Catalunya, 25 minutes walk to the Gaudi museum in the other direction, and 15 minutes walk to Segrada Familia. The closest subway stop, L5, is only one block and 2 minutes away. The neighborhood itself is pleasant - good local bars and restaurants abound, and are much lower cost, relaxed and less touristic than the center. The only drawback is street noise - for those of you light of sleep it can get a bit loud in the morning.
