I am giving myself 3 weeks in a designated small walkable Italian city with easily manageable day trips via public transportation - in October.
I had 2 weeks in Verona last year, happily loved every minute. Verona happened quite by accident; beyond Shakespeare, I'd known nothing about it. The size, the walkability, the sites and sights were perfect for my wishes. I walked about ten miles every day. I have had the same experience with Nice.
I was in Florence for six days as many years ago and had planned to spend my vacation there again this year. Due to lost luggage for five of the six days, some of that trip is a blur. Do have a hotel booked. However, I have seen a number of less than enthusiastic posts on the Florence forum re Florence being too crowed, too touristy, not for a longer stay... and I am suddenly wondering if I should look elsewhere. I will be 70 in October, traveling solo; am not interested in renting a car; like having an easily accessible airport.
And so I thought I would ask if there are any such Italian cities I have overlooked or if the Florence naysayers should be ignored.
