Comfortable, clean apartment and very well located near Place Catalunya. From the airport, it's quickest to take the Aerobus, which gets you to Place Catalunya. From there, it's a 5 to 7 minute walk to the apartment.
There's a grocery store right next to the building and a bigger one a short walk away. The metro station is close by and there are abundant eating establishments and shopping nearby.
All in all, a great place to stay in Barcelona.
