Giovanni is a lovely welcoming host; we arrived late because our train had broken down, yet we didn't have any difficulty checking in.
The place was absolutely spotless and perfect for our last night before flying back to the UK; it is right next to the main train station and the airport shuttle bus stop.
I would not necessarily choose that area though if I was coming for a city break in Naples as the neighbourhood is not the nicest. I would also encourage the host to leave a little bottle of water in the fridge especially during the hot Italian summer :)
