If you need a car rental in Oman, please run away from AST Oman!
Really bad service. The car was delivered 2 hours late at the airport (with no one from the company to inform us, and anybody being reachable by phone) but, above all, they still did not refund our deposit of 150,00 OMR that they committed to refund by 21 days at the latest (we’re now more than a month and a half from the end of the rental). We are chasing them every week, with nobody considering our request seriously. Honestly, there are many other providers for car rental in Oman, so contact someone else to save you troubles.
