Hiroya really tries to make your arrival easy. When you book a room, you have access to a 33 pages pdf document (!!) describing how to go the house and how everything works there.
The location can seem a bit far away from the center, but after an evening at Shibuya or Shinjuku, i was so happy to go there (in 20 minutes) and find this really quiet house. The rooms are small and pretty dark (i was on the ground floor), but it s Tokyo. There was everything i needed in the room (even a USB plug). i had a very pleasant stay there.
