The location was perfect, the flat was very clean. It's pretty and the bed is excellent. But there was a major problem with communication. First Giuseppe took five days to answer my message the week before arrival, making me wonder if there was a problem with our reservation, but mostly we could not reach him on the day of our arrival: our plane was one hour late, so I sent him a text before take-off and another one after landing to let him know our exact time of arrival, using the phone number he gave on Airbnb. No response. As we arrived at the apartment the first thing his wife Ada told us was "You're late !": she had not seen the messages!
Same thing on the day of departure: Ada kindly told us through Whatsapp that we could check out later (11:30am) but Giuseppe showed up at 10h45 AM looking almost angry and saying "You are still here??" We showed him Ada's text and said that we were ready to leave if he needed the apartment but he just said "You close the door and wait for Ada". We felt really uncomfortable and just wanted to leave at that point because we felt like we were bothering our host but we waited for Ada, and at 11:25 she sent us a text... she would not come and we should just leave the keys on the table.
At check-in Ada also forgot to mention that a window was broken and we were very cold before they fixed it (it snowed), but we realize that snow and cold winter are not usual things in Naples.
All in all it was a pleasant stay but bad communication with our hosts definitely was a source of stress and frustration.
