It was a great staying overall and we would recommend it for a short or even medium staying in Naples.
The assistance and the communication were excellent, with several checks that we were ok, the luggage deposit they have is absolutely a plus (consider it if you have a flight or a train late in the day, is very convenient!).
Wifi is adequate to check emails and reservations.
Double glazes windows are excellent to keep possible noises outside and the AC will ensure a comfortable staying.
In the flat there was a pleasant vanilla fragrance, which we could not detect where it was coming from, but it was nice (much appreciated it!).
The location of the flat is close to Main Railway station, Metro and bus, making easy to arrange travelling in the city.
The area (opposite to the first impression) is very quite, with lots of shops managed by Indians who sell semi-precious gemstones, and we actually took advantage of it!
Near the Porta Nolana, there are several groceries open till late in the night, making easy to buy water and some fruits even late.
There was just one detail that we have already clarified with Salvatore:
The cleaning fees are not evident in the first page of airbnb, and they are explained in the House rules, which we did not really checked honestly, and they will be reminded once you have completed the reservation: Salvatore explained that this is because the cleaning is managed by a third party. So please consider an extra
30 euro for 1/2 persons (check-in, cleaning service, fresh linen kit) / 35 euro for 3/4 people (check-in, cleaning service, fresh linen kit) and they should be paid cash at the check-in.
Overall, a great staying!
