We recommend this place !
Everything was perfect : room is super clean and quiet, the breakfast is simple and good (and Stefano even bought us a gluten free breakfast !), Stefano gave us really good advices to visit Napoli ! The flat is near the train station. The suburb is not the best in Napoli but metro and train stations are very close which is very convenient to visit the city and the area (pompei, salerno...) !
Enjoy your stay !!
