Giovanni's studio flat is very attractively decorated with thoughtful attention to detail and can't be faulted. Everything works well and is clean and comfortable, including the bed.
It's all well-run too, and Giovanni's mum is a homely presence.
We chose this location because of its close proximity to Centrale railway station (5-10 minutes walk), realising that it is a bit of a rough-looking area. However, I felt quite comfortable there and did not perceive any sense of threat. It's noisy if one opens the window, but that probably applies to almost all of Napoli, and the soundproofing of the closed window is very good. I would highly recommend this place, especially for those wishing to travel (Pompei, Sorrento, airport, etc.).
