Can someone help me with which agencies are really close in Yonge/Finch?

Have a friend visiting, we want to have separate 30min appts and then switch girls for another 30 mm.  Although its easier to book two girls from the same agency, the girls I want to see are at different agencies.  I'd rather have the same buliding...anyone know if zenful, toe88, moonwaiting bulidings are same or very close?  Please PM me if its too much to post (don't tell me the actual building, just want to know how close it is to walk from one apt to the next for visiting friend new to GTA). If you PM me, I will share any info with anyone else who PM's me.  Tough getting the logistics right for this mission.
