We had a lovely stay at Federico's apartment. Although it looks great on the pictures, the pictures don't do it justice and it very much exceeded our expectations. For instance, the apartment is much more spacious then it seems on the pictures. The 2 bedrooms are big, approx. 25m2 each and like most of the apartment have high ceilings. The whole place is tastefully decorated throughout as you can see on the pictures.
Must have in Napoli during summer months is air-conditioning, both bedrooms and the kitchen feature an AC unit which kept the place very nice and chill.
The apartment is situated close to piazza Garibaldi, conveniently close to the metro and train station. Small price to pay for this is that this place at daytime is buzzing with traffic, which, although a lot less of it, you can hear at nightime, but it's as quiet as you can expect in a big and crowded city like Napoli.
Federico and Vittoria were very attentive, welcoming and nice people, and having contact with them in person or via messaging was a also great.
Overall we had a great time at this apartment and would definitely stay there it if we visited Napoli again.
