It's a small apartment, comfortable for one person. The location is great, entrance of Catacombe St. Gaudioso is front of the building and the Centro Storico is also 10-15 minutes by walk. Vicenzo is a kind and helpful host. If you want to spend your days in the heart of Naples for a reasonable price, this is a good choice.
There are no WiFi in the apartment and it is also very dark because there aren't any windows.
