Teru was a Super host (would have given him 6* is there was any available). He was friendly and chatty; hospitable and even invited us to his abode for dinner (certainly a first for me after several Airbnb stays)! Queries to him were answered promptly and he was able to give clear instructions, in English or Chinese ... your preference.
His place is at Yochomachi (a few mins walk from Wakamatsu-Kawada station and 2 stations away from Shinjuku-Nishiguchi station) which is super convenient to walk to Shinjuku Gyoen Park, Shinjuku etc.
Mattresses though stacked high was comfortable and amenities esp. heater, in the apartment was available to keep us warm. Apartment is clean and would certainly return to have our next stay there .... Thanks Teru!
