Kan was very responsive and flexible. He let me leave my bags early before check-in and allowed me to leave my bags after check-out for pickup later. He was always responsive to all my questions.
The house is indeed, a tiny house. It is, however, well designed to take advantage of every nook and cranny to make it functional for a small footprint. It was very practical for my needs as I needed a place to cook some meals, sleep and take a shower. Kan lives there and so the kitchen was stocked with pots/pans and spices. The rooftop deck was perfect and I enjoyed the the view from there during the day and night.
The neighborhood is very affluent and quiet. There's hardly any noise at all and very few cars come through. It's a 5 min walk to the nearest Metro station and supermarkets. The location is great for Tokyo as well, usually 20-30 mins away from all the attractions and shopping.
