This is an unstaffed, tiny apartment with its own bathroom (toilet, shower head, small tub). The beds are on the hard side, and there is only one small pillow per person. It was definitely cramped for four bigger Scandinavians, but that is probably the case everywhere in Japan. There is a heating element for a stove and a hotel-sized fridge, so we were able to make coffee/tea and eat breakfast in the apartment. There is also a washing machine, which was an awesome feature for us. There is a grocery store about a block away, which was great. The manager of the apartment was very responsive over email when we had questions. The apartment is located in a non-touristy and safe area right next to a subway station, so it's convenient to get around. If you stay here, make sure to check out the best sushi place we found in Tokyo, which is right around the corner to the left when you walk out, it's called Mihiro Sushi.
