Great location right on piazza. 200 years ago, one could have looked out the window at the original David (as opposed to the copy now in that spot). Ufizzi is next building, Ponte Vecchio steps away, short walk to Duomo and Academia.
Good cafes for breakfast. Great porcetta/prosciutto places on next block for other meals.
Apartment is clean & bright. Not too noisy with windows closed, so don't worry about that.
