Just a suggestion
Favorite thing: Just a suggestion if you are planning on doing a lot of walking...don't wear high heels (if you're not used to them)...because it is gonna be hard to walk. Especially on the cobble stoned streets.
Just like any other town
Favorite thing: Foča is pretty much just like any other little town. And yes by that I am refearring to hills. But it's something you get used to after a while :)
