The flat is perfect for a short or longer stay. You have everything there you need and the rooms are spacious. The kitchen is handy, new and clean. You can make yourself a coffee, tea (water and juice) whenever you want, for free. The flat is naar the metro station Materdei, 5min. walk and a longer walk to the city center, 15min. Santolo and Sylvia are perfect hosts, their breakfasts are legendary and enough to have lunch too.
A nice value for money place to stay in Naples, specially if you travel with a group of friends. The check-in was a breeze thanks to the helpful owners. Silvia and her partner are very nice people and made very nice breakfast for us next day, including special requests for vegan options, plus fresh home made coffee. The B&B is 5 mins walk from Materdei metro station. I would highly recommend.
