The Gracia neighborhood is really lovely - close to everything one needs - the flat accessible and was spotlessly clean. We were a bit surprised to see the living space quite small and a bed laid out (not a sofa bed that could be converted) and it turned out to be not very comfortable. The bedroom is however beautiful and the bed there is very comfy and nice. The flat would be perfect for a couple. This is the fist airbnb home we stay in where there is absolutely nothing in the kitchen in terms of basics such as salt, pepper etc. There is a supermarket down the road - so be prepared to stock up on literally everything.
We were only staying a couple of nights and had some issues with a couple of items /facilities but due to our busy schedule didn't notify the host until late. Their response by mail was quick and positive although the issues could not be fixed before we left early the next day. I can recommend this nice flat for the location, comfy bedroom and cleanliness.
