This is not an Airport hotel but does provide view of the aproach to the airport from a holiday resort from a significant (30km) distance .
We where allocated a room on the fourth floor, any even room number works, booking a sea view will get this. The third floor if all else failed would work as still above the tree line around the hotel, but requesting a high room with sea view should get the 4th floor.
I have attached a photo of the view North from the hotel room (432), departs from TFN (When on West Depts) would appear climbing from behind the ridge in the distance. I've never had them land that way, but I would expect they are even easier to see. Clearly low cloud would be the only problem on a lousy weather day!
