Nice place with value-able price to stay in Tokyo!
Walk-able distance to Shinjuku Station (around 13mins) ; 2mins walk to Nishi-Shinjuku (M07) which is very convenient too.
There is a Familymart nearby with 2 mins walk only; also a supermarket in 2 mins walk.
The place is quite spacious and completely ok to open 2 28”inches suitcases!
