This apartment was okay for our stay. The view is phenomenal, and the location is pretty Central to most things in Florence. The main thing we didn't like was the church bells in the morning at 7am every morning. I think it's like that everywhere in Italy, but it was particularly loud here. Also, the water heaters in this building/apartment make a very loud beeping noise, so whenever anyone in the building showered, there was an annoying beep. The rest of the apartment was fine - although we were only left with half a roll of toilet paper, so we had to go and get more ourselves.
I would recommend this place if you want to be in the middle of the tourist action, but keep in mind the noise that comes with it.
