This is easily one of the best Airbnbs I've stayed at. It exceeded all expectations.
I will start with my only warning that I think travellers will appreciate. It is technically a "shared space" so the sound barriers are not perfect. but this is to be expected. Expect that loud noises from you or others will be heard throughout. Though in my opinion, you would be silly to let this deter you.
Now for the positive aspects:
It is an excellent location, minutes from shopping, food, and misc. stores. The area is beautiful and considered one of the best in Naples.
The service and communication was excellent. Raffaela and Giovanna ensured that I was comfortable and accommodated in every regard. Everything is available in the room (for purchase) if desired. There is free espresso available in the Foyer and you get a free breakfast (your choice of a caffeinated drink and a pastry) within walking distance from the apartment.
It was the cleanest place I've stayed in Italy. There was a cleaning service daily, for fresh sheets and a general wipe down. The furniture is up to date, stylish and comfortable.
The cost is extremely reasonable. For the area, the service, and accommodations, it is an extremely fair price.
I highly recommend staying here for a trip to Naples. I look forward to coming back knowing that a stay like this is available.
