First and foremost, the owner was really tentative and helpful. He answered all my questions and even helped to book ke a taxi to the airport upon checkout. Instructions were also clear.
Now about the location, it is quite a walk away from Shinjuku Sanchome station but quite near to Higashi Shinjuku. However Higashi Shinjuku line access is quite limited to our destinations which means more train change. But the unit is located just behind Shinjuku area. Easy access to convenient stores and the lift really helps.
About the unit itself, it will comfartably accommodate 2 adults. More than that you will have to squeeze through the areas. Only 1 large sized luggage can be opened at any one time. The unit also lacks hanging area/rack inside. There is hanging line outside though if you don’t mind. Cooking amenities was enough as well as dining. The bathtub was quite small but maybe its common size in Tokyo. The hot water was stable.
All in all we do enjoyed our stay. Thanks!
