Very clear instructions on how to get to apartment as well as using of the room and appliances. Very easy check in process.
Apartment was very clean and host very responsive when we requested for more towels.
Lift and apartment space is small, so not ideal if you have very large suitcases. Would recommend 3 adults as a maximum for comfort. Ideal for 2 persons.
Location is extremely convenient (7-10min Shinjuku stations) and is near a really great udon joint!
