Declining accommodation offer??? And reapplying?? should i?? too risky?

I got allocated meadow courts, the rent is nearly 130 a week.

I think it is quite expensive, and thinking of getting something cheaper.

Should i decline the offer, and reapply? or is this abit of a risk, that i may end with something i really don't like?

How do i re apply for accomadation? Apply again online or somthing else?

thank you
