This was our first time in Naples, so I think we might have had the wrong assumptions, but please note that only 1% speaks English here (and that may be generous). We ended up leaving 4 days early with no refund given. I'm not entirely upset about it - we should have done more research on the area to be honest.
The short is, the place is super noisy (city center = motorbikes surround you until 10:30pm), water is not potable (water bottles were provided thankfully), hot water never ran for shower (??), WiFi was mostly reliable, entrance smelled of dank mold (not in the actual flat, thankfully), and check-in happened only by chance since we happened to meet a gal on the bus that spoke limited English that led us to the area, then chatted with the local residents until one knew of the host. She was a relative and happened to have a key to let us in (thank the stars!) Since the host never attempted to meet in person.
I would highly recommend the place (for the price) only to native Italians who know of the area. I would not recommend to vacationers/tourists (or Honeymooners like ourselves) - unless you are in a shoestring budget with plenty of time to get lost and nowhere else to go.
