This place is in a good location -- close to the major areas of Shinjuku if you want to see the neon lights, and you can also walk to the Tokyo Metropolitan Government Building for a high up view of the city. The room was clean and it was easy to communicate with the hosts.
As a side note, the only way to dry laundry is by putting them in the bathroom and turning on the heater, which might need to be left on overnight if you're drying lots of clothes or heavy clothes like jeans, etc. So, start drying your laundry after you shower for the day.
All in all it was a good stay!
