I will be in Florence 3/21 and would like to see sunset at Piazzale Michaelangelo. Sunset should be around 6.30pm so I would like to arrive around 6 to soak it all in. I have seen others post that it is a reasonable walk. Our hotel is near the Uffizi. Does anybody have an estimate of the length of time that walk would take? Is it a nice walk or would we be better off taking a bus or taxi?
