Apartment is clean and spacious. However, be aware that the surrounding neighborhood is not very nice and we felt unsafe walking around there especially in the afternoons when the sun went down. Also be aware that the host will only supply one roll of toilet paper in each of the two bathrooms for the duration of your stay. We were a group of 6 girls staying for 5 days so this was a little frushtrating for us since all other air bnbs we stayed in this week supplied all we needed for the duration of our stay.
Also be aware that you can not make any noise while traveling up the stairs to the apartment. On several occasions we were yelled at by people living in apartments below us while we were walking up the stairs even when we were whispering and being mindful of our noise level.
Local tax will have to be paid when you arrive. For us it was 2 euros per person per night and this is not included in the price you pay for the air bnb. Also be aware that the host says you can’t drink the tap water. We were supplied with two water bottles and then after that you have to make sure you supply your own. Overall, we had a good time in Naples.
