A very good stay for a small group. We had 4 but I think this place would fit a group of 3 more comfortably. Still manageable nonetheless.
The location was fantastic; 10min walk to the main Shinjuku Station and it is located in a rather quiet neighbourhood with a nearby supermarket & FamilyMart.
The place was clean and cozy; everything you need is provided and the bed was comfy.
Definitely recommended!
