The house is beautiful, clean and stylish for grup of 12 person is good.
River san is very responsive to any question. It is located very near to convinience store for your daily needs.
The nearest station dont have an elevator on the east exit, so if you bring a lot of luggage you may need some muscle to bring your luggage downstair....
Other than that River's place is outstanding, we would like to stay again in the future.
