Oftentimes an airport hotel is simply a hotel convenient to the airport that also has a shuttle bus. The Hyatt Place is more like a hotel designed for air travelers. They have all the electronics you need to check your flight, check in, etc., 24 hour schedulable shuttle (Portland's early flights can be VERY early) and they pack a box breakfast if you need to leave before their (free) breakfast opens. The box breakfast does not contain a beverage. I thought this was an oversight until I realized you can't take it through security anyway, duh.
If I were to voice one complaint, it's that while the rooms are quiet and comfortable with excellent AC, the windows don't block out the airplane noise very well. Make sure to ask for a room facing away from the runways
