The apartment is nice for one or two people. I was happy about the location, which is down the street from the steps that lead up to Piazzale Michelangelo. I was able to walk everywhere too including the tourist sites. There are nearby restaurants and the bus is about a 5 minute walk, which you'll need to use if you're coming from the station.
I stayed in early October and the building and first couple nights were quite cold and uncomfortable for sleep (and I'm from the Pacific Northwest). I wish there were more options for covers during this period and I know the host tried to make it better for me afterwards, which made it at least more comfortable for the nights.
