Koichi is a true Superhost! We were truly touched by his hospitality. He went above and beyond for his guests. He was flexible when we changed our arrival time, picked us up from car rental shop after we came back from Hakuba, spent half an hour on the phone trying to find a gym for my college age son when we arrived at apartment, and dropped us off at the gym since my son wanted to catch some training time before closing. Saved our luggage and brought them to train station when we were leaving, he specifically found an subway entrance for us that has elevator, not to mention insisting on carrying luggage up and down stairs for two ladies in the group.
Loved all goodies he left in the fridge for us, quite location in the middle of hustle and bustle Shinjuku. Rooms are spacious for 4 adults.
