A simple appartement with a great location in the city in a pedestrian street.
I would recommend.
5 mn away from the metro station and in front of the funicular ststion.
Apartment is very simple but practical.
The main advantage is the Terrace with a very nice view and a fridge with free beverages.
Only drawbacks are the elevator to get to the flat (so hot and strange) and the air conditioner which is too loud but useful if you want to stay there in August like we did.
We spent a week in Napoli and we were very satisfied.
