10/10 Highly recommended. This has been by far my best Airbnb experience. Beryl is very friendly and nice and her tips are very helpful. E.g. once she found out that we are museum nerds she recommended the Naples Artecard and it came to be very helpful. She made amazing homemade​ breakfast for us, everyday a new different dish, they were soo good that I could not resist asking her for their recipes. The apartment is accurately described and everything is tidy and clean. It is equipped with all the necessities from toothpaste to shaving foam. This let us to travel light and pack our bags with Neapolitan Taralli instead :P. Their backpack also came to our help when we wanted to climb Vesuvius.
Beryl was also very nice for being flexible with our check-out time.
Unfortunately this time I did not stay in Napoli long enough to see everything, so next time I will definitely stay at Beryl's bnb.
