I recently stayed here for a night and it was a decent, practical airport hotel.

The hotel is situated between the airport and Narita town. There is a complimentary shuttle bus which leaves from stance 16 outside terminal 1 and stance 25 outside terminal 2. The timetable is below.
The hotel also offers a complimentary shuttle bus to Narita town. The timetable is below.
Arriving on a bus, a lot of passengers wanted to check in at the same time. Fortunately, checkin was smooth, as was checkout the following morning.
The staff were polite.
I stayed in a twin room. It was clean, with excellent curtains which blocked all external light and a comfortable bed.
The bathroom was a bit ugly, with a lot of plastic and poor lighting making it hard to read in the bath. The amenities were also light, with no cotton buds, for example, and a painfully slow kettle.
I was planning to use the gym and sauna but discovered that it only opened in mid-afternoon. So although the hotel did have a decent run of amenities, their utility to me was low.
The hotel was not especially charming, but it was clean and comfortable. It was reasonably though not massively convenient for the airport.
