Space is small but easy to accommodate our family of 4 with our teenagers each having own room. No drier but laundromat 1 minutes away if you are in a hurry otherwise cloths line under cover and dies easily.
All the basics you need and close to lots of cafes and Nishi-Shinjuku-gochome station is 4 min walk. Very peaceful, neighborhood. Highly recommend. Chikako met us and also slowed early check in , much appreciated.
