Great stay overall!!! The stay was very clean and accurate to the description. We stayed for 5 days, and it was very convenient for our work, and going to other places in the Tokyo area. (5 minute walk to the nearest metro station, and 15 or less minute walk to Shinjuku). The Nishishinjuku area is also very nice and there are a lot of good restaurants and bars within 10 minutes walk!
The bed was comfortable and all of the appliances worked perfectly…
It is next to a hospital or some place with a lot of ambulance traffic, which can be loud but I never had any problems at night.
Overall a great stay and I am incredibly likely to stay here again in the future.
