We had a very good stay, it is not perfect, but it is very good.
Location wise it was perfect for us, a quiet street in the middle of Gracia.
The apartment is very nice and well decorated, internet works very well and all works well.
Just two recommendations to achieve the perfect score:
Solve the smell that comes out of the kitchen sink, sometimes very bad smell.
Bigger TV, it is just Two far for the size of the room.
With those things solved it would have been perfect.
