If you know the Vila Gracia area in Barcelona, then you know it's very charming with all its small streets and gives you that local feel.
Lots of bars, supermarkets, restaurants in the neighbourhood.
The only thing you have to understand is that the walls are very thin, so noises in and outside the building are easily heard. In the autumn/winter season this is not a big issue, but during warmer season people will be more outside and create noise.
