The apartment is in an apartment block in a moden residential area right on the border with El Raval. La Rambla is close by (less than 10 minutes walk), about the same to Mercado de La Boqueria. Also very convenient if you're coming to Barcelona by train -- it's 3 or 4 stops on Metro. It's a bit of hike to restaurants and attractions in El Born and Latin Quarters but it's a pleasant walk.
The apartment is in great condition and has all amenities, even a washer/dryer -- good for families. While not super spacious, it fit a family of 5.
