Kaoru is such an awesome host! He responded promptly to our messages and was super helpful if we needed anything. We really enjoyed staying at his apartment and wish we could have stayed longer. His apartment was extremely clean and had all the necessities and more. The size of the apartment was also much bigger than expected. This is also a great location for everything in Shinjuku with access to other parts easily. We will be sure to return here our next time in Tokyo.
