An absolute must in Florence if you can book this appartment, if you can’t I suggest you change your travel dates. The view of the Piazza della Signoria is gobsmacking morning noon and night.
The appartment itself is modernly designed with Italian flair and very practical.
In terms of location, it’s difficult to see how you could do better.
Federico is a very attentive host- all done from a distance but it works well.
