Very nice, warm and efficient greeting by Montserrat.
Overall we had a pleasant stay in this flat which is comfortable, reasonably quiet (except for some barking dogs in the morning) and large enough for 3 or 4 people without any problem.
The best point is its perfect location just at the border of Gracia (so cute village-like area) and eixample, at walking distance from most locations and a few minutes walk from at least 3 subway lines. So if a central and charming location is important, this flat is for you.
On the dark side, the problem is that the flat is... very dark ! With no view at all. There is a film on the windows from which a gloomy and pale light tries to enter the living room. A real pity not to be able to see the crisp blue sky of Barcelona (one has to open the window and band the head up to see the sky). So if light and view are an issue for you, this flat is not for you.
Also, for the price, the equipment of the kitchen could be upgraded (coffee-machine, toaster, real spoons, some small plates, wine glasses...) as well as the plumbing system (we had some hot water issues once in a while).
