An amazing place and location. We had 6 travelling together which is a great number for the size of place.
Right in the middle of everything you need. 10-15min walk to Shinjuku main station 6min to Shin-Okubo station and everything you need right outside your door. Located in the middle of the markets you have great food and stores right outside your door.
Ichimaru was a great host, the place is self check in so we never met but any question we had was responded to promptly. Would happily stay again.
