We had a horrible stay, inaccurate listing and for what it costs it's at the level of a hostel.
The place is in a bad state: too much humidity and no windows, full of dust, strong smell of sewage coming from the toilet, no hot water so we couldn't have a shower. Also the place wasn't very clean, we found hair in the sheets, full garbage bin from previous stay, a half used bottle of shampoo as a hand wash, very old lumpy pillows, the internet router was broken.
Avoid to avoid ruining your holidays in Naples.
