This was not as we expected.
The flat was different than on pictures. We asked about the differences between photos and reality and after that we were told that the flat from pictures has pluming issues and he needed to move us to the different flat. There was only bed and bathroom there. No Wifi, no air-conditioning, no microwave or anything else from description and photos. After few days host brought fridge and microwave and tried to provide WiFi, but failed. WiFi was working for a day, and then stopped and we couldn't use it for the rest of the visit.
Address was also different than we were told. We were driving around the given address in taxi for few minutes to finally find our host, who then lead the way to different place, which resulted in us paying more money for taxi and wasting more time.
Host doesn't know English, so we could communicate only with AirBnb chat with translations. He replied fast, however the information he was providing was not always correct. Few times he promised that, for example, someone would come to fix WiFi in the morning and then nobody came. The same situation happened when we was supposed to bring us the microwave and the fridge. We were waiting during the morning (he told us the day before that he would come in the morning) and he didn’t show up. When finally we decided to leave the apartment and wrote him on the Airbnb chat, he replied that he was coming in the evening. Without any apology or explanation. We were wasting our time waiting for him instead of enjoying our time in Naples and sightseeing. Moreover, in the middle of the visit he claimed, that we need to pay him 28 euro tourist tax, which we refused, as there was no information whatsoever about this before our arrival.
Location was nice, close to the old city center. However, the street was really loud and with luck of air-conditioning we had two choices. Either leave the windows open and couldn't sleep from the noise, or close the windows and couldn't sleep from the heat. Tough choice to make.
To sum it up - we do not recommend. Flat was different that in photos and description, accommodation was nowhere close to what we expected and the price was too high for such standard.
