We really enjoyed being in Gracia where we could dine like a local at one of the squares while our kids joined in a game of kicking around a soccer ball; yet we were an easy walk to Sagrada Famillia and not far from other Modernisme sights with easy Metro down to El Bon etc.
The space is exactly as pictured except that the building is gorgeous with some details that don't come out in the photos. The facilities are modest but completely functional. Small kitchen has 2 burners, microwave, toaster, clothes washer. Small bathroom has standup shower with good water pressure. The twin beds are rather firm and don't have a separate door. Our kids got a kick out of the curtain setup but if we were four adults looking to spend a week and cook a lot of meals there may be better options. The large table in the main room is very functional. Lay out all your stuff there and you can always find it. The street is not very loud (for Barcelona) and the windows and shutters can shut out most of the sound and all of the light. If you are sensitive to light when you sleep you should know that the main bedroom has a window facing into the building alcove. There is a curtain that shades the light well and we didn't find the building to be loud with people coming and going. When we return to Barcelona will will certainly consider re-booking this home.
