Susanna is a wonderful and communicative host. I wish I could have stayed longer! Everything was very clean and the location is perfect both for living longer term in Florence and shorter term. My university unfortunately made me leave Italy early, and she was incredibly kind. If I have the opportunity to return, I'd stay here again in a heartbeat. :)
My only light warning: The staircase is steep, so make sure you're very careful--especially if you have large bags.
