Location: 5/5 it is perfect to where it is 2 mins walk from the shinjuku busy streets and approx 5 mins from the train station! There is a 711 within 3 min walking distance.
Amenities: toothbrush and 1 laundry soap, everything is clean and tidy. Just remember that there are only stairs and no elevators. This was informed to us.
Check in process: quick and easy and responds quickly. You do have to email your passport information due to japan laws.
Highly recommend for a quick trip to shinjuku if you are not going to hang out in the room. Directions are clear too.
