Hard to say. Five minutes if you ran the most direct route but that could get you killed.
It seems there is a lot of police attention all over. The assault on Ascar's place is rather high profile- you can see in the distance that they have three hovercars just outside his office, vollying in fire inside.
Chion is NOT the trusting type... though he would be unlikely to kill you himself. He just thinks the Jedi will make mincemeat of you. There ARE certain personality traits to be learnt about Chion if anyone dares.
You would think Chion makes you easier to spot. But actually, he can be REMARKABLY stealthy when he needs to be. Unless he is next to you, of course; then he is hard not to notice. He tends to scrape though doors as well.
Also worth reminding people of his appearance- albino, bright white with horrible red eyes, with pulsating blue veins running over the length of his body. His head is bald but the veins all come together to some sort of knot at the back of his head. He wears primitive furs.
