I'll have a short overnight layover at NRT during an upcoming trip (arriving in the evening, departing in the early morning the next day).

I assume I can't spend the night in any of the airline lounges, so I guess getting a room somewhere close to the airport would be the most convenient option.

Does anyone have experience with this place? http://www.apo-resthouse.com/english/acc/ Is the hotel actually inside the airport? The website seems to suggest this, but it also mentions taking a comp. shuttle bus. (I'll be arriving on AC and departing on NH)

Any other options I should consider?

Thanks in advance!
