Sane's place is a very clean appartment. Sante is a really flexible and friendly host.
The Monti neighborhood is probably one of the best places to stay for a short visit: we stayed here 3 days an haven't used public transport at all :-).
The flat is small, for a couple for 2-3 days is very good and comfortable, but not really for more. What I have to emphasize is the very good quality of the bed in the bedroom!
As for the kitchen, you can drink nice coffees, and have a nice breakfast, but otherwise, the kitchen is quite basic (although nice), don't expect to cook meals here. The fridge is also a bit too small even for such a short time, but it is okay also.
The flat is very clean, you have everything there that you would need for a short visit. I would certanly recommend Sante's place!
