if your a big spender than a salary of 10000 OMR wont be enough,id depends on life style.
some who worked here before will recall (post office) cafe days
and some will remember how the blew away all their savings
f3ss,u will always have the choice here in muscat,to find whatever rent u want,no adays u can even live in barka which is only 15min drive from the airport for peanuts.
not like on your side space is very limited.
