Ken is a wonderful host! Prior to booking his place, I contacted Ken and asked tons of questions, and Ken thoroughly answered all my questions in a timely matter.
The apartment is just as described. It is a small apartment from an American standard, but, as a single traveler, it was more than enough. Ken prepared pretty much everything you'd need while on a trip, such as towel, shower gel, shampoo, conditioner, hair dryer, and etc. The apartment also has a full kitchen with pots and pans, etc. in case you feel like cooking. Ken provided a portable wifi with unlimited data so that I was able stay connected with people and navigate myself while I was out. The apartment is about 15 minutes walk from the nearest train station, and it takes about 30 minutes (if you transfer to the rapid express train at Shinyurigaoka) to Shinjuku station. The train does operate past midnight, so I was able to take my time sightseeing and shopping before returning to the apartment. There's a 7-11 and a groceries store (closes at 1:00am) by the train station, and a 7-11 and a groceries store (closes at 9:30pm) by the apartment.
Ken picked me up from and dropped me off at the train station. Upon checking in, Ken explained everything thoroughly and showed me around the place. The next day, I received message from Ken, making sure that everything's alright with the apartment. Ken was able to make recommendations on transportation and places to visit. I appreciate Ken's hospitality and would recommend this place.
