The apartment is in an absolutely fantastic location in the city centre, less than 5 minutes away from the metro and Casa Mila/'La Pedrera' and close to many shops, bars and restaurants. We loved how attractive and characterful the apartment was, especially sitting out the balcony.
Staff very warm, friendly and helpful. Breakfast buffet available for €8 from the main hostel or you can do your own thing - there's a nice cafe right in front of the apartment building. The hostel has a bar and restaurant attached which you can go to.
It probably doesn't quite come into the "deluxe" category though as it does need some improvements: the sofa(sofabed) is quite old, saggy and uncomfortable as a seat (we didn't use it in its bed function), however the main bed was very comfortable. Living room in general was a bit bare and uninviting but we didn't mind because we were out exploring the city. The windows let in a bit of noise due to its location and having single-glazed windows: the internal ones of which happen to be right next to the neighbours (we had a noisy, annoying neighbour).
Needs a few changes making for it to be accurately described as deluxe, however, given the excellent location, balcony and beautiful interior for the price we paid, we were very happy.
