Raffaele is a great host! He gave us all the usefull information to Napoli and suburbs and was always available to provide any help or information.
There are 2 metro station in the near of this flat. One you can get just in 3 minutes the other in 8 min. It takes about 35 min to get to Napoli center (Piazza Cavour or Garbaldi). Notice: after 22.00 there is only one opportunity to get home - by taxi (costs about 20-25 eur). Public transport - 1.20 eur one way.
One station from Bagnoli you can find volcano "Solfatara". It costs 7 eur to go in, but nobody check it up. For 7 eur p. P. we have got just a paper brochure.
There are a lot of small and nice locations around. Pizza (Il Bricconcello, Pizzeria Giuseppe) for 3-10 eur, pasta (Bricconcello), tapas, cocktails and local beer (Birrificio Flegreo).
In Napoli you can feel you home, because of the friendly and nice people around.
Thank you Raffaele for this expirience!
