When I stayed at Jambo in a savannah view studio, it was way out on the Kidani side of Arusha (I think the room # was 5377). I remember what a long walk it was to get to the elevator to go to Mara to eat. So I'd suggest asking to be close to an elevator to Mara. There was an elevator not too far away, but it only went down as far as the lobby, by the back doors, they told me, so I had to walk a long way to get to Mara.
