The apartment is great. In particular the view is amazing. From every room you have stunning views on the city. The apartment is just as on the photos. We came in the end of November so it was a big asset that the apartment had a proper heating system.
The area is not right in the center but still a very nice place, with lots of local shops and bars around. Just 150 meter away you find Starita one of Naples most famous pizzerias. You can reach more central areas by a 20 minute walk or have 2 metro stations nearby.
Salvatore was also a very nice and welcoming host. He told us about things going on in the city (exhibitions, food festivals) and he lives just one floor beneath - so if you need anything he is right there.
