Lovely apartment, obviously recently kitted out and the outside area is great. There is a pizza restaurant on the same street which is very good if you don't fancy walking far for food one evening.
Location wise it was easy to find and is close to the train station and very walkable to the main sights of Florence. Being slightly away from the crowds was a benefit.
The only issue for us was the noise from neighbouring flats. This isn't the hosts fault and is just symptomatic of being within an apartment block. TV from next door is audible in the bedroom at night and talking/walking around from the flat above. If you're a light sleeper it may be a problem.
