Very nice flat to stay in, as already mentioned in the comment, there are a few steps to walk to get to the flat but it is very nicely renovatew and clean.
The air conditioning helps when it gets too warm and the little balcony is nice for mornings and evenings.
The walls are thin, but everyone is smart enough to pay attention to the noise in the building.
The area around the flat is super chill and it is lovely to stay around in the neighborhood for tapas and drinks or walkable to other areas in Barcelona.
Thank you!
