Kaen's place was a good place for me during my week long stay in Tokyo. Kaen communicated very well and made the travel to her place and check-in as smooth as possible.
The location is very quiet even though you are a block away from Koreatown. I love the convenience of having two train stations nearby and several 24-hour restaurants and convenience stores in the neighborhood.
While small, the space had everything you needed if your objective is to spend as much time exploring Tokyo. The outdoor patio is a huge bonus. Kaen provided clear and photo instructions for how to operate all the appliances and controls in her home.
