I was satisfied with my staying with Michele's. An apartment could not be situated better from geographical point of view – right at the center of the city, so it is very easy to reach any attraction within Naples or take a break from walking and charge the mobile. The flat itself is of minimalistic design, with white walls, high ceilings and a perfect window-view to St. Clara. However, the street behind the window is full of noise (tourists, street musicians) for the whole day. Thus, despite the beauty of the location, you should not hope for tranquil sleep and happy mornings. The bells of nearly situated churches is, of course, an exception.
Our communication was perfect. Though Michele lives in the next room, we did not disturb each other at all, and thanks to his courtesy I barely noticed his presence.
P.S. There is no heater in the room and the central heating is turned on just for several hours a day, so in winter it is always very cold. Sometimes might be even colder than outside. Funny to say, on the first day I warmed up only after I had gone outside.
