The hosts are fantastic and the apartment is wonderful. The hosts take very good care of the place and their guests. I felt the apartment is well equipped with all the items needed for doing a little cooking as well as soaps, laundry detergent, and nice soft towels.
As you'll see in the pictures there is a very nice view out of the kitchen window and the location is great for getting around the city. You are very close to the main walking streets of the older part of the city and also a very short walk to Corso Umberto which I consider a pretty main street in the city with many shops and restaurants, which you'll also find right on Via Duomo; and pretty much all over Naples... I found walking the city very easy from the location, but there is a bus stop right at the intersection of Corso Umberto and Via Duomo and the current closest station "Universita" is a short walk down Corso Umberto. (Google says 10 minutes but it felt even shorter to me.) Just a little info I found helpful; the standard day passes for public transportation in the city covers Linea 1 buses, metro, and funiculars. There's another option if you want to travel outside of the city too. They're also building a new metro station right at the intersection of Corso Umberto and Via Duomo that's scheduled to open sometime in 2020.
I'm very much hoping this place is available for my next visit to Napoli and highly recommend it.
