we will be walking around central Florence, near Santa Croce, Uffizi, Palazzo Vecchio, etc, and want to take Bus #12 or 13 from that area up to Piazzale Michelangelo and San Miniato. I can't seem to find out if there are stops and/or where they are in that part of Florence. I am hoping we don't have to go back to the bus station to board. Can anyone confirm that there are several stops in the area around the river, either on north or south side, that we can find? If so, where? And are the scheduled stops frequent on those routes during the mid afternoon week days? Thanks so much for any help! Also any hints or suggestions regarding how best to include in our visit the church vespers with the monks chanting?
