Our family of 5 spent 8 nights in this beautiful house and would thoroughly recommend it.
The house: Brand new, super clean and clearly well made with lots of really nice small touches throughout. 2 cosy double bedrooms with additional sleeping available in living area. AC works great - 1 per bedroom and one in the living room/kitchen.
The location: Excellent location to explore Tokyo - really convenient for both the Metro and JR Line. House is on a really quiet street with no traffic, but is <1 minute walk to local convenience stores, cafe's etc. Countless great cafe's and restaurants within 5 minutes walk.
Host: Ami was a great host. Always responsive and helpful via text. Has clearly put a lot of thought in how to make the stay enjoyable (portable WiFi, local guide etc.)
