The house is cozy but easily fit our group of 7 adults in the 3 bedrooms (3/2/2 split). Convenient access to the main JR Yamanote Line within ~6-8 minute walk for access to nearby hotspots like Shinjuku, Shibuya, etc.
The household is in a calm neighborhood though relatively close to some train tracks which introduce some additional noise -- though not enough to wake us up with the windows shut.
The ceiling clearance could pose an issue if you are in excess of 6' tall.
The decor was wonderful, and immersive and a guidebook is provided with recommendations. Overall wonderful place.
