I would say its approximately 20 minutes drive to the city palace and about 15 minutes to the centre of Jaipur.
It is not very central, but do you really want to be in the center of this mess? if you going to the town just for couple of days there is no need to be in the CENTER, the ride to the center is very cheap and for 20-30 ropees you get there, just past the traffic, more likely a zoo. I didn't think it was necessary to be at the center, you rather want to be in a place with less noise and better air quality.
