Good places to stay near CUSB Gaya?

I’ll be visiting Gaya in January with my girlfriend. She’ll be joining CUSB (Central University of South Bihar) soon. We’re looking for places nearby to stay for a week or so. Checked Maps, didn’t find anything good in 15-17KM radius. All good AirBnBs and hotels seem far off or close to Bodh Gaya. Any suggestions from locals or CUSB students will be helpful.
