Simona's apartment is in a fantastic location, close to the center (duomo) area, and still on a quiet residential street; it is a very secure and high-class building with doorman most of the time. Simona is very nice and very sweet and helpful and responsive. She lives next door so that makes it convenient. Her communication is very good and she was willing & able to accommodate us even though our plans changed last minute. She kindly left us things for breakfast, and there is a good brand coffeemaker if you are into that. There are two balconies and nice views.
The apartment itself has some beautiful touches (paintings, woodwork, bookcases, marble floors, etc) but it could also really use some updating. The tubs are both very old and don't look very enticing to bathe in at all. The kitchen is functional but everything is old and a bit sticky as happens with older apartments. The a/c is only in the bedroom and it is an old unit that you have to figure out and it leaks into the floors so you have to put a dish under it and if you run it at night you have to get up in the middle of the night to change/empty the dish or it will overflow and spill all over the bedroom floor. At the time of our stay the shutters in the living room and bedroom were stuck shut and Simona told us they had been broken and she was in the process of getting them fixed/replaced.
Overall we had a nice stay and Simona is great but be aware that you are not going into a sparking-new apartment with fresh amenities - it's more like staying at your grandma's place.
