Guisi could not have done more to help. Due to some confusion, I think Guisi ended up having to wait a long time for us to arrive. We felt awful but she was nothing but smiley and welcoming. We could not have asked for a more attentive and helpful host. Guisi really does take the trouble to help and make you feel as though everything is covered (she even helpfully offered us a driver from the airport though we ended up taking the bus).
The apartment is everything that you could want - it's as central as you could possibly get for all of the sites. We wondered from the apartment to the historical quarter within about 2 minutes everyday and it certainly made everything easier.
The place is comfortable, warm and feels safe. Having the addition of a safe in the flat and having Guisi a phonecall away was a real comfort.
There was a little bit of noise from some work going on in the main building but Guisi apologised about this and it really wasn't a problem at all. Other than that, there was something very special about hearing the bells of the church in the morning whilst getting ready for a day's adventuring.
We would definitely, 100% recommend this apartment to anyone. Absolutely great value for a couple visiting Naples (and probably wouldn't have felt too crowded with an extra guest).
A++++
