Looking for subrent for summer internship starting June 15th

Hello everyone! I am looking for a 1-bedroom or studio apartment subrent from June 15th to August 23rd in Princeton, NJ. I will be going back and forth between the place and Siemens office. My budget is ~$1500/month. My preference would be close to downtown or near Princeton University as I don't mind commuting to office. I am open to any suggestions. Thank you!
