Hi,
Take the road behind Borokids, it's at the top of this road. Frankos will be on your left and the Blue on your right, keep walking til you get to top, ask where the medical centre is and it's in the same building.
Have fun.
Queenie.
It's in the building of Bulgarian Mountain Rescue, you can walk up from the gondola and when you see the PSS Building walk around it and left from the terasse is the entry door with a big sign Bobby's Bar
