Attic Motel is about a 20-25 minute walk from the terminal, although they apparently have a free shuttle and there was an MPV outside with their branding.
All rooms face towards the threshold of runway 10, i.e the corridor runs along the back of the hotel. Makes it nice and easy. 4h/5th/6th floor. I was in 503 which was great for spotting. Too many obstructions like lamp posts and trees, as well as the hotel windows, for photography.

Note it is against Taiwanese law to photograph military aircraft.
