Donna's place was great. We had plans that took us all over Florence and Donna's place was central to everything, never more than a 15 min stroll even when we were heading to the furthest away points.
There are quite a few stairs, but we got used to it. There was a bit of noise outside in the middle of the night, but it didn't bother us too much as we sleep with headphones and white noise.
Donna gave us great food recommendations and it led to our favorite dinner on our entire trip.
It was great to have a washer and dryer (though we mostly used the drying rack) and a good sized fridge to keep water cool.
We had a great stay and would stay at Donna's again.
