So I decided to stay at Toni's place for my last night in Napoli after disappointment with hostel-stay and after reading all the good reviews and yes, it was one of the best decisions. I booked very last minute but Toni was very communicative and arranged my checkin with Fabiana, who is also a very nice and friendly lady. Basically all went smooth and in order. Regarding the apartment, I love it. Centrally located, walking distance to the harbour and historical center, clean, has everything you need and you get to experience living like a local, as it is right in the middle of those typical Neapolitan narrow streets. It was a pity for me that I didn't manage to meet Toni in person as I left for the airport early the next morning but I for sure will come back and stay over again next time I visit this beautiful city.
