This place isn't a room, it's a house! Very comfortable for 2-3 people or families with small children.
The neighborhood is quiet, perfect after a long hectic day of travelling.
Amenities-wise, pretty much everything you need is covered. We stayed here in the Spring (6-9 April) so the weather was pleasant by then, but the room still felt a little chilly as there wasn't a heater. However, we're from tropical Malaysia so those accustomed to cooler temperatures might not find this to be a problem - especially since Kaori provided very warm blankets!
Every morning, Kaori prepares a delicious home-made breakfast to get you going!
If you're planning a longer stay in Tokyo, this is a place you should consider.
