We recommend a stay in this place for 100% and would return to it for another stay in Naples. Among the many good points, these are the highlights:
1) location - from this location you can walk the historical center and you have a metro within 100m for everything else 2) quiet - Naples is a busy, noisy town but this roof apartment is above all that, literally too. A quiet place is very important to me and Vittoria's place is very much so. 3) view - the place has a 360° view on the surroundings, including the Vesuvius, Vomero hill, mediterranean sea and historical center. 4) comfort - Vittoria's place has everything you need, from bed, shower, fridge, fireplace ... and is very tidy and comfortable
There are no lowlights, just a few things you should know: 1) the 360° view is from the inside, you won't have access to the roof terrace 2) there's no closing door between the bathroom and the main room, so you will see/hear the toilet from the bed 3) the elevator goes to 5th floor and then you take a few more stairs to the roof apartment, the elevator works for free during building closure but needs 20 cent coins during office hours - the apartment will have a couple in store. 4) Vittoria can text in English but you may need some knowledge of Italian, or else work your way through conversation via google translate. 5) although the apartment itself does a triage of plastic vs other, the bins downstairs are all together, so you should really only triage cardboard/paper and glass (which goes in a bin outside the block).
Some tips about the neighbourhood: 1) the small shop-restaurant next doors is very good, friendly owners, yummy food - it closes at 7:30 like other shops 2) there's a small supermarket in the via dei Cimbri straight onto the door; you can find anything there but the owners are rather rude 3) there are two pizzerias in the same street where you can take away; the one closest, on the left side, is much better than the farther one on the right side
The value of this apartment is incredible, Vittoria is a wonderful host and Naples is a town to cherish.
