I stayed at Giovanni’s place when I went to Napoli v Manchester City.
I flew from Ireland to Rome and got the train to Naples so being able to get off the train and walk for 3/4 mins to Giovanni’s was great.
The room was super clean, the shower was amazing. I was greeted by Giovanni’s sister (?!) who had little English but nothing that google translate couldn’t do.
There’s Wifi, the double bed is big and there was genuinely nothing that bothered me.
I did have to walk 25 mins to the port but if I had have stayed closer to the port I’d have to walk 25 mins to the train station so it’s much of the same.
Would recommend to any traveller who has to use the train station for sure.
