The location for this airbnb is ideal if you are looking to stay in the busy neighboorhood of Shinjuku. It's really close to a metro station which makes it easy to access other parts of Tokyo without too much difficulty. Communication was really smooth and the people we met at the desk were very helpful.
However, the room turned out to be very shabby and we were surprised to see such a difference between the photos shown on the website and the room itself. It was clean enough but it was a lot older than the photos, so I personally felt that the description was not accurate. We didn't stay anywhere else in Shinjuku so we might not be aware of the average condition of hotel rooms. But considering the price, I personally don't think this was worth it.
