Carmine is the best host I've ever met.
And an accommodation is very clean, even a shared bathroom is perfect, seems like it's properly cleaned twice a day.
Carmine provides great breakfast and even makes a Choco cake himself.
Apartment is perfectly located in very centre, 3 minutes walking from SM Novella station, next door to Mercato Centrale.
Mercato Centrale is a must to visit, go to the second floor to discover great Italian food and wine in very nice atmosphere.
