This was a great place to stay, and particularly good value. It's located at the very heart of Naples in the vibrant old city between the 2 [mostly] pedestrian streets that seem to be known as the Spaccanapoli - so an exciting location, and under 15 minutes walk to various useful & interesting places including the Duomo and the metro; and about 20 minutes walk to the central station.
Raffaela provided some handy provisions which was an unexpected bonus, and having kitchen facilities is very useful (fridge, hot plates, sink, toaster, kettle, coffee machine, crockery & cutlery etc); this also makes takeaway pizza a good option; there are (printed out) details of some local restaurants etc provided.
Finally be aware of the narrow spiral staircase to reach the bathroom, this could pose a problem if you have mobility or coordination issues (or: if you get drunk!)
