The airport is quite aways from the city center.
There are a few hotels around I think but not much else. I would be a real bugger to do that commute everyday.
If your company is sending you to work at the airport I would definitely get them to locate you suitable place to live (but I don't think you want to live out there, its pretty empty...google earth it).. Mr gf use to work out there and the commute by local bus was 1.5-3 hours depending on traffic or a taxi is about 40-50 minutes and cost about 14-15$ dollars each way.
Your better off living in Hanoi and having your company cover the travel expenses, but your still going to spend almost 2 hours a day to commute.
Good luck
