Shu's accommodations were *perfect*. A small loft apartment, suitable for a solo traveler, couple, or two to three persons maximum. Three adults would be a very very tight fit.
Shu provides a capsule-style coffee maker (and a personal tutorial on its use), towels, bedding, and there were coffee capsules, milk powder sticks, sugar sticks, and even a couple of bottles of water in the fridge :-)
The loft bed is very sturdy (I weigh ~160lbs/72.5kg)... but he'll make up a futon on the floor for you if you'd prefer. The apartment is also enhanced with a lovely garden (ground floor) out the sliding glass door, a separate bathing room and toilet room (with bidet), and kitchen with fridge, microwave, and induction cook top.
The building is less than ten minute walk to either Yokota AFB to the East or Fussa Station to the West. Also within walking distance are several delightful restaurants, including a delectable curry eatery right across the street (that also does take away!!!) as well as convenience stores, Ramen houses, drugstores, shopping markets, Mcdonald's, and more.
You don't need to rent a car while staying here, that's for certain! And Shu was lovely enough to come pick me up from base after the shuttle dropped me off even though it's a fairly straightforward walk.
I give his accommodations the highest possible recommendations, and Shu himself even higher for his quiet kindness, respect, and dignity.
Thank you and look forward to seeing you again, Shu!!!
