Santo Spirito, as i think a few have pointed out, gives you a welcome breather from the tourists yet it can only be a hundred yards from the Ponte Vechhio.
It is popular with students and with the locals (nearby are some delis and whatnot so you actually see Florentines) and comes to life after nine or so in the evening.
At the top of the square is Brunelleschi’s spectacular church - as well as having a crucifix by a very young Michelangelo, it was studied and admired by many including Da Vinci and it is easy to see why. It is especially pretty when the facade is lit at night.
There are a few restaurants and a couple of bars in the square, the type of spots where, if you drink too many amerettos, they give you a tequilla on the house - the atmosphere is friendly at all of them.
Istayed at Antica Dimora with a friend but it would be especially nice to go there romantically - ask for a room with a little balcony. You can watch (and listen!) to the market being set up in the morning. The rooms are huge with lovely wooden beams and, maybe vaguely kitsch decor but it feels like you’ve been to Firenze! It’s a short back street walk to the wonderful, wonderful Bobili gardens too.
