Positive:
Very good location, close to the famous Sorbillo pizzeria, restaurants, street food (we recommend the vegetarian crostone place on the left of piazza Miraglia). Also the prices of those places was quite reasonable, lower than in other areas.
Great value for the money.
Great shower, with plenty of hot water and proper shower cabin. The bathroom is in general very good. We appreciated the shower gel, shampoo and soap.
Very large bed!
Neutral:
The illumination is a bit dim, in december, but not a big deal.
It was difficult to connect to the wifi, we had to set static IP addresses.
The apartment is very big for the price, but it has a strange layout, which makes it less usable than it could be. Anyway it was good to have the sleeping area separate from the kitchen.
Upon arrival, it may feel unsafe because the area is very dirty, messy, worn down and the apartment has a an unusual entrance and safety bars at all windows. However, after a day, we felt at home, nothing happened to us and we felt safe and we loved the area.
Negative:
The apartment is accessed through steep and narrow stairs, which arrive directly in the kitchen, so that one has to be careful to not fall in. Probably dangerous for small kids and too narrow for a buggy. Also, it was uncomfortable to lock the door from inside because the space for doing it was dug in the wall.
Very humid. Of course this may be common in Napoli. The bed sheets were humid when we arrived; however, just removing the duvet from the sheets made them better. After two and a half days our laundry was still a bit wet, even if it was hanging close to the heaters.
