Great place if you just need a place to sleep and cook some basic meals. It's right in residential neighborhood 2stationa away from Shinjuku, one of Tokyo's busiest commercial district.
Room is simple and cozy, though many will find the bathroom is very tight, even in Japanese standard.
Pocket wifi is available for use, a huge plus for any international guest! Just make sure to bring external batteries when going out, it's battery won't last 1/2 day!
