Great location, walkable distance to Shinjuku (around 15mins on foots). There are restaurants, convenient stores and supermarket nearby. Yuka-San is also a great host who has responded my queries quickly and helpfully. She changed the hair dryer next day after I have reported to her the hair dryer was broken at night. However, maybe because the house is near restaurant, there is a strange smell at 1st floor and the room is not as bright as photo one.
Yuka-San, thank you for your hosting!
