Amazing apartment! The layout is great with the bedrooms downstairs and the kitchen and living area upstairs. The main bedroom has a little lounge and tv area which is a great touch and not overly common for Japanese apartments. One bathroom (and one toilet separate) can be difficult with multiple guests but not really an issue if organised. The location in Koenji is great. 2 minute walk to a Family Mart convenient store and great little resturants between the apartment and train station. The apartment is tucked away in a little alley which was a little tricky to find at night, but is nice and private and the instructions to get in are very simple. The beds are quite firm, as most beds in Japan. We had 3 people stay here and it was very spacious, so can easily get 5 people in comfortably. Kitchen is well equipped. Air con in main bedroom and upstairs and heated rugs for winter. Pocket wifi was very handy also. Would definitely recommend this place for a family or 2 couples. Great stay!!!
