Ken and Masa's place is located in the perfect area. It is very close to the train station and a few stops away from Shinjuku. The apartment is a bit small. We were traveling in a group of three and the space was adaquate for us. The common area/kitchen space had a round table that took up most of the space with not much room to move around. The bathroom had a separate toilet area with a bidet and a door to separate the shower. There was also a washing machine so you can do your laundry. Also, please note that the apartment is on a 4 floor walkup with no elevator. Overall, a great place for the cost.
