Sabbatical in Florence

Hi there,
I am Birgit from Germany and I am looking for a place to stay during my sabbatical with the university of Florence from Oct 1st until March 15th or so..
I have been living in Vancouver, Canada, for 3 years during my post-doc and I am very familar with and I enjoy sharing space with other people, as long as I have a room for myself where I can be on my own when I want to.. At home in Germany I live in a house with my twin boys who are with me half of the week and with my dog Betsy. During the first week of November they have public holidays in school and they may visit me in Florence (or I'll go there).
From October to March I will spent 10 days in Florence and then 4 days at home with my boys which means I will be away every second week for 4-5 days.
I am fine with any space which exceeds about 8 qm, that is providing space for a bed, a desk and a closet.
I do not smoke, I am humorous and am liberal.
Please get mack to me if you like this description.
Warm regards, Birgit
