This is a nice, large apartment, exactly as described and pretty good value for money. Everything for a short stay is there and nearby there are plenty of shops and places to eat. The area is pretty residential, so quiet at night, and is well connected to the city centre by bus and metro, while the beach is within walking distance (~25 minutes though there is also a bus).
We were attending the Primavera Sound festival which the apartment is great for as you can walk to and from the festival site in under 30 mins and avoid queuing all night for buses.
One complaint would be that the bed is not particularly comfortable and if one person rolls over the other almost gets bounced out of the bed.
Overall a nice place to stay, recommended!
