As advertised, the flat is located in the very center of Naples and everything is at a walking distance, from the port to the Museum of acheology. It is also very clean and well-equiped. The only drawback is that it might be a bit noisy as it is just up one of the main street of the city. But the isolation is good enough and you can sleep well.
Davide welcomed us warmly and gave us good advise about the city. He was very flexible about the check-in and check-out time.
I would definitively recommend this flat if you want to explore Naples.
