Interesting. Do you have photos of these hostels you can share in this forum? I heard accommodation is limited.
The cheapest one we know is the Lagoon View (kindda run down already so we think it's unsafe for students) and the one nearby, Belvedere (I think much safer than Lagoon View) both you need to walk or wait for the shuttle bus. Lagoon View is cheap but the last time we visited the water tank was bursting with water and the neighborhood doesn't look appealing so I wouldn't advise students to stay here.
At Belvedere, I have met a few students living in this apartment. Most units are unfurnished and the pool is rather quite small if you think of it. Parking is also limited.
Another option would be the houses near the area, they turn the whole house into a student hostel. At Ibilik, I am quite impressed on how they furnish the rooms.
