The flat is located close to Toledo station, in the center of Naples, in walking distance to the Spanish quarter, Spaccanapoli and the port. There were also grocery stores in the neighborhood.
When we arrived, we were greated by a colleague of Giuseppe, she showed us the place and also gave us some tips to the city. The flat was sparkling clean and looked just as described on airbnb.
The flat itself is located on the 4rth floor of the building (no elevator) this wasn't an issue for us, but might be something to consider when you book.
