I'm a graduate of INTI Subang. Used to stay at a shop lot accommodation that's located at the same row as McD. Rent is quite high but because it's only 3 mins walk from campus + everything is included in the rent (wifi, electricity, laundry, cleaning, etc). Landlord is really nice and helpful and the place just opened in 2015 so it's relatively new. I was the first batch to stay there so I had all the new Ikea furnitures lol

Other cheaper options would be Rajawali, the apartment building right next to the campus or the other surrounding houses that rents out to students. Some of the houses rent out rooms for RM500/month but be ready to share the space with at least 20 people. Do PM me if you want to know more.
