The flat is exactly as described and as shown in the photos. It is newly renovated and we found everything we needed and more: the flat comes with a fridge, dishwasher, wash machine, gas stove and microwave oven. On top of that the flat is fitted with 3 very nice and state of the art TVs, two of which have Android TV and allow you to watch programs like Netflix, etc. if you have an account.
Our hosts have been very generous and thoughtful, some additional nice touches we really appreciated: we found some basic groceries (i.e. salt, sugar, coffee, detergents for the dishwasher and wash machine, etc.) as well as nice sets of freshly cleaned white towels, shower gel, plus much more (iron, hoover, cleaning products, etc...)
The flat also felt very safe: it's in an old (historical) building, on a third floor and there are two strong doors leading to the flat in addition to the building main door.
One of the highlights is the location: the flat is in the old city center, just 2 minutes walk for the Archaeological Museum and 5 minutes from historical landmarks like Piazza Dante, Port'Alba, the church of "Gesu' Nuovo" and Santa Chiara. And there are so many more: Spaccanapoli, access to "Napoli sotterranea", the local music conservatory... the list is really endless.
The area is also crawling with cafes, bars and restaurants, some of the best and oldest in the city. For example "Starita a Materdei", a very famous and great pizzeria, is literally 5 minutes walk from the flat.
Finally, while most of the historical and artistic attractions of the city are within walking distance, the flat is also close enough to two metro lines as well as the "Funicolare di Montesanto", a cable car that will take you to Vomero, as well as the "Cumana" railway, which takes you to a number of very nice locations on the seaside north of Naples, many worth a visit like Pozzuoli, Arco Felice, Baia.
The apartment is great for a couple or for a family, is very comfortable and we would definitely recommend it to anyone. We will probably stay there again if we visited Naples.
One note for families with small children: since the building is very old, the elevator is very tight and you might struggle to carry bulky strollers or luggage in it.
