The apartment is very clean and Emanuele is very helpful with everything you need. Apartment is in secured building with nice view on Napoli. The building is in (at least in our opinion) not 100% secured location, surrounded with strange people. But we didnt have any exact negative experience with them (just feeling). Train station is located 5min from apartment and by the train you can reach Vesuv, Pompei, town Sorento, etc. Emenuele recommended us all interesting places in Napoli and we took his advices gratefuly.
In general we enjoyed our stay in Naples :)
