lovely apartment, nice comfortable room. it was a last minute booking, and i know i wouldn't have been able to find anywhere nicer for the price, not by a long shot. the best pizza i had in napoli is a short walk away, and so are some nice cafés, bakeries, etc.
my only complaint is that it's in a strange area that doesn't feel entirely safe walking to at night, and it's fairly far from anything a visitor would be interested in unless they had a car. having a lock on the room would also have been better.
i never met Giovanni, but he was perfectly communicative and reasonable over text.
