Book this now! If you are worried about it being expensive, don't.
What you pay is way less than what you are getting in terms of service, cleanliness, well maintained apartment rooms with a nice theme, and hospitality.
The Kawano family go above and beyond if you are stuck in a situation where you may need a ride to the station or if you need some extra time before checkout as long as you tell them in advance.
My group of 4 friends would highly recommend this place and all agree this is the best airbnb experience we've had. We are extremely grateful to them and would book their place again with no hesitation.
Thank you Kawano Family!
