The apartment is lovely. Just like nonna's place. More nostalgic than trendy !
The person who managed the rentals was super-helpful. We could not figure out how to turn on the electric stove, and didn't have a lighter, so he popped over with a new lighter for us so that we could cook on the gas stove instead. Also, only one of the bedrooms was ready when we arrived (due to a previous problem with the roof) but within 30 minutes he had a set of fresh sheets for that room. He was really great.
The neighbourhood is close to the train station and within 15 minutes walk of the more touristy parts of central Naples, which is great. There are also bank machines and good grocery stores nearby (look for the Supero!).
However, the area between the train station and the apartment is a bit sketchy, so best to arrive during daylight hours if you are a woman travelling alone.
