Incredibly convenient to Haneda airport. From the airport, go down one story to the subway, take it ~ 4 stops to Otorii metro station. It's a 2 block walk from the Otorii metro station. You get a code to get in and out of the guest house (so there's no curfew). The women's bunks have a good amount of space, a light, a plug to charge things, comfortable mattress, pillow, warm blanket. There's a small locker (sized for a phone or passports), but no luggage locker. Great wifi signal.
