Our 5 member family spend 10 days in Barcelona at February.
The main advantage of the place is location in the city- we could reach many places by walking. It is just on the crossing of two main roads but in the 8th level, there is hardly no traffic noise.
The whole building is full of apartments for rent, so it has more hostel feeling. There were few really loud parties in the house, especially on weekends nights.
The apartment offers everything needed but no more. It has same hostel feeling like the whole building.
The best value is big terrace with beautiful view.
The digital key worked well.
Our stay there was ok, but next time we would prefer another place.
