When I just moved to Malaysia to do my Foundation in Science, I stayed in hostels for one whole year before moving out to an apartment in Starz Valley when I started my degree.
The monthly rental of the apartments range from RM 750-1600 depending on the type of room that is being rented. There are 2 bedroom apartments available and also single studio apartments.
The main reason I chose to move to Starz valley from hostels is because it is only 10 minutes walking distance away from INTI IU. Also, I am able to prepare my meals which was not possible to do in hostels since we were not provided with a fridge. My monthly expenses round up to about RM 1500.
If you are planning to move out from hostels to an apartment, make sure you weign in all the pros and cons before doing so.
