This place is the best and so is Viky! First of all, Viky is very welcoming. She send me a message before arrival, on how to get to the apartment from the airport.
Her apartment is very well located, in the heart of the Quartieri Spagnoli. The metro station is very close by, but you can also walk from there to discover the beautiful city of Napoli!
The apartment itself was big, the bed was very good and the shower is very nice. Although its situated in the (fairly noisy) city centre, you don't hear much inside the room (very good windows).
Viky send me a list of restaurants where I could eat, and there are many restaurants in this neighbourhood. Any other questions were answered very quickly by Viky on whatsapp.
I had a lovely stay and would book this again.
