Very cute and cozy place, and extremely convenient in the downtown area of Florence. It is on a side street of the Duomo (a bit further than just two steps) and right above a cafe/ bar. Most nights that was okay, but weekend nights got a bit loud. The cafe itself is nice, we enjoyed some nice lunch and breakfast there.
As others have stated, it is 100 steps up the stairs, so just be aware of that when you have to carry your luggage all the way up. But it was well worth it: we were there during a heatwave and the air conditioning kept the apartment nice and cool.
There is a washer, very convenient. No dryer, but laundry dried overnight, which was very helpful. There were some things that I missed, like extra toilet paper, paper towels, dish brush, etc, however, there is a small grocery store right down the street where we could pick up those extra items.
Besides that, our stay in Florence was wonderful! Thanks again, Fiametta!
