Ken was very accomodating and replies quickly to any questions. He also provided a very helpful video to get to the apartment to make things simple. The apartment is perfect for a big group and is spacious compared to other places in Tokyo with a kitchen. The beds are also very comfortable. However, there are lots of noise restrictions in the apartment including ensuring that suitcases cannot be dragged up the stairs and that the windows must be shut if you’re talking near them. Consider this when travelling with a big group.
