Had an excellent stay at Junya's place - rooms are private with access by lift and the floor comes equipped with its own toilet and wash basin. The room is very stylish and spacious with plenty of closet and floor space. We also love the decor. Room is equipped with a powerful aircon/heater which is much appreciated during winter. Also very clean and feels new.
The place is very accessible and close in proximity to Koiwa station, which is a direct line/short transfer away from Shinjuku/shibuya/akihabara. For its price, it is a fantastic deal.
