We stayed at the apartment for 3 days and everything was beyond our expectations! It is located in a quite residential area yet in a walking distance from the city centre. There are a lot of places to eat around as well.
There is an elevator in the building.
The apartment itself feels and looks very stylishly decorated and has everything you need, including coffee capsules and a bottle of wine kindly presented as a welcome gift by Manel. Also he was available for any issues that we had during our stay that made us feel super welcomed.
We would choose this apartment once again if we were visiting Barcelona in future.
