Hi Van,

You get the Housing irrespect of where you live or how much you pay. The Housing allowance is reviewed accordingly. So the answer to your first question is yes you keep the balance of the housing allowance if you manage to find a cheaper accomodation and vice versa if you find something more than your allowance you have to top up ur self.

Second question. you get paid flight to you base country, irrespect of if you travel there or not.

Good Luck..
