Kazanlak is a town in central Bulgaria.
Kazanlak is a small city so it's easy to walk everywhere. You need to go along the street Rozova dolina (Розова долина) down to the store Billa, cross the bridge, continue straight (even though there's a sign showing to take the first right after the bridge - continue straight!!) And then on your right you will see a ramp going up, this is the spot. There's no special place for stopping, but Bulgarians (if they want) stop everywhere. From the main Kazanlak square it takes around 15 minutes to walk to that spot. Usually it takes up to 5 minutes to get picked up.
