Thank you Kentaro-San for your hospitality! Location was great for a young travelling family. Large local playground a couple of blocks north, 15 mins walk from the ueno park and zoo to allow your little ones room to spend all that pent up energy!
Also only 20 mins or so from the hustle and bustle of shinjuku & shibuya. Even allowed for a late checkout so our 2yo could have a nap before heading to the airport. Thanks again Kentaro!
