First what is your parameters for äffordable" and what do you consider "good", air conditioning, fan, refrigerator, concierge? What exactly do you expect?

Try going to hostelworld.com or a Vietnamese site like http://www.hotels-in-vietnam.com to get an idea of the options, then come back and ask what others know about your preferences.
