This is an apartment where somebody actually lives. It has nice, cosy atmosphere. Mind that it is on the 5th floor with only steep flight of stairs. Guido is very welcoming and helpful host. The apartment may be too hot in the summer nights, but air-conditioning may help. The position of the apartment is very convenient. Though it is 15min walk to the train station, use metro when having suitcase, because it is hard to drag it on the cobble stone streets of Naples :)
