Me too, I don't see the problem with Hahn. Much better than Erfurt or Zweibrücken. Next big city is Koblenz what means 80km drive, what is very reasonable when you fly long range.Ryanair flies in from dozens of destinations, so it is really no problem at all getting there. If you want to live there, as I said. Choose Koblenz. Beautiful city, not far away.
