The apartment is great- especially the terraces!
The location is in a local neighbourhood, so it's a very authentic experience well away from the touristy areas. A bakery, supermarket and Metro station are just around the corner, which are super convenient.
Being only 5-6 Metro stops from the Gothic Quarter and El Born, we found it very easy to get around and explore the city.
If this apartment is available for your visit, snap it up- you won't regret it
