The house is perfect for a family trip. The neighborhood is as convenient and quiet as the host described. It's about 5 min walk to the nearby station and is surrounded by convenience stores and restaurants. I think it's quite hard to find such a spacious accommodation in the CBD area.
John and Ritsuko are so thoughtful that they provided us with detailed transportation information and tips, which are very useful for the first-comers. And they are always reachable with timely response.
I would high recommend this house.
