My friend and me stayed at Serafina's place and it was one of the best experience. Serafina and her husband were very welcome. They gave us a detailed directions how to get to the apartment, that was situated next to the shopping street and Piazza del Plebiscito. Also, 10 mins walk to the old part of Naples. Despite of its location, it wasn't noisy at all.
The room was very big, clean and equipped with all necessary amenities. The breakfast was quite rich and Serafina's cake was just delicious. The hosts gave us tips what to see, do and eat in the city. They were always ready for help.
If you want to feel at home, you should stay at B&B Mariela :) If I go to Naples again I will definitely stay there:)
Thank you Serafina and Raphael for making our stay so unforgettable :)
