The neighbourhood grazia is perfect, its actually my favorite location in Barcelona. A lot of little stores, bars , good food, very creative area with a lot of friendly people. Two metros are a couple of minutes away so you can get to anywhere pretty fast.
Imma welcomed me and my cat very well, she made sure I have everything I need and helped me to get around the city. The room is great its very private and everyone that lives in the house are extremely friendly and nice.
