Waseko's place was just 2 stops away from shinjuku Station. Waseko was fast in responding to our enquiries and needs. The place from the JR Takadanobaba station was not really a walking distance as it is 1.5km away from the station but fret not, there's a bus station right in front of the house if ur not a fan of walking. But kudos to Waseko for being such a nice host to my family and I.
