Firenze is really worth a visit - a very pleasant city.
About the hotel: the hotel is located 6 or 7 stops by tram (ticket costs 1.50) from the main train station, the area looks friendly, there is a large supermarket only about 200 meters away, but there are also a few other late night shops.
The hotel itself is 2* and for a 2* it's actually pleasant (but more on that later).
The reception is in the basement (-1), the lady there was friendly.
You then go up a flight of stairs (no elevator) to the room - but the staircase looks also friendly and freshly painted.
The room itself seemed gloomy, because it didn't have its own window, but the room next to it has a window.
This "next room" also houses huge boilers, which I have never seen anywhere else before in a Hotel.
Then follows another room: the bathroom.
Sounds a bit weird, and it was.
The bathroom was bright, clean and had a window.
Otherwise there was a wardrobe, a desk, 3 beds in our double room, a fridge and AC.
The AC is really important because the room itself had - as I wrote - no window.
You shouldn't open the windows in the boiler room or in the bathroom, because then you attract mosquitoes - but we were able to kill them.
What was really positive (and I'm very, very picky): everything was absolutely clean. You could eat off the floor. Also the bedsheets and the towels were clean and there was a good smell also in the staircase (a bit artificial, but good).
