We always stay here the night before our flight just for convenience. I think this is my/our fourth time in the past couple of years.
Along with the convenient location, the hotel has a great atmosphere, a great bar with a lot of selections, a solid menu with very non-typical hotel food (in a very good way), and is a short walk to EDI. One could easily spend multiple nights here and be very comfortable and happy.
And if you face the airport, you can watch the rabbits come out of the grassy, wee hill in the evenings.
