In the middle of the bridge there is a gap between the shops, enabling you a great view of the river and the buildings on opposite banks.
You should also make sure once you're done visiting the church to take a few minutes to walk around its lively piazza.
Behind the palazzo you will find the Boboli Gardens - a nice place to relax enjoying beautiful views of the city.
A nice way to end the visit is to go for a quick walk around the palazzo's garden, and perhaps stop by the special modern art exhibition if there happens to be one.
