Hey - Its not that bad. You can get some thing decent with two bedrooms, good enough to live in Le Mirage Residence. They have couple of building. The area is not super good but buildings from inside are good. They have proper kitchen and it would be easy for you.
There are other buildings as well who can offer you the same kind of deal but I have not seen them from inside. I just stayed here. Apart from that, if you are coming with 4 kids, and you want to live in some decent and nice area you can get a 3 bed room apartment ranging from 10K to 18K, depending on your choice of area and apartment.

Also if your company is giving you a one bed room apartment then I would suggest you come alone for a month and have your family here within a month. If your PROs are smart, you will have your RP in 15 - 20 days. Then you will look for an apartment and can have your family here once you get the apartment.
Hope that will help.
