We stayed at Virginias apartment for 10 days and really enjoyed our time there.
The apartment is perfectly located if you want to explore Naples by foot or take the metro/vesuviana (~10 mins walk) to go to other destinations around.
The highlight of the apartment is, of course, the big terrace which gives you a quiet opportunity to calm down from a busy day. All other rooms are nicely furnished and the kitchen is fully equipped.
I'd recommend staying at Virginias apartment to everyone that is able and willing to walk up a lot of stairs every day (you will be rewarded with a great view) :)
