We found this apartment matched its description and our expectations. We were met by host, Marina, and welcomed. It is easy short walk from the station (we came from Florence, and Marina provides an easy map) and extremely convenient for our trip next morning to Pompei (5 mins to the train to Pompei). While the area is next to the extended street/fish markets and pretty raffish, this is also interesting and it is short walk to the historic centre and we walked to the old castle areas and fine shopping as well - which was really buzzy a week before Christmas. And a great time to go, weather was great.
Marina's recommendations for local restaurants were great - went to da Donato's twice for excellent meals.
Apartment is modern, very clean and well appointed, and safe. There are plenty of local food shops just over the Corso Garibaldi for shopping to eat in, incl wine etc. We walked everywhere, incl to the national museum but there are easy metro options close.
