A central stay with is good for a few nights. Julia was always available if needed.
The building is quite old and there are quirky things you may or may not appreciate. (Like the lift), which works fine but Julia’s place is on 2nd so you don’t need to rely on it :)
We could hear trains running underground in the late and early hours but overall if the neighbors are good, there will be little noise.
Basic provisions are provided.
Overall, very nice stay in the center of Barcelona!
