If you arrive from Shinjuku train station with large luggage, suggest taking taxi (around 1000 yen) to get to the place (1.6 Km).
For some reason the taxi driver couldn’t find the address from his car GPS. I have to use my google map to guide the driver. It seems the address provided by the owner is for a block of buildings. “
5 Chome-2 Shinjuku, Shinjuku, Tokyo”
The room is very small for 3 people, no space to stand after putting on the 3rd sleeping pad. No chair to sit.
The bath room is tiny but okay, there is no smell issue reported by previous guests.
