The house is pretty straight forward what you see in the pictures and floor plan is what you get. Its big for a family of four, 2 adults and 2 teenagers. We used the room on the first floor as our walkin closet so no need to bring all the luggages and because the bathroom is also in the first floor. I must say that I was surprised with the restrooms, it has three unusual for Japanese houses.
It is near restaurants, a ramen house and korean restaurant and a caffe. its very near the Mikawashima station just follow the pictures going to the house. It has all the basic things that you would need in a house. If you plan to cock though buy the basics, cooking oil, seasoning and all. This is not provided.
The down side for me is the distance to all the other tourist spots. Like coming from Harajuku, Shinjuku and Shibuya you need to travel 10 to 12 stations and transfer to go to Mikawashima, that will easily consume more or less and hour one way.
Overall the amount of rent versus everything else is just right. I would recommend the house for big groups with time to spare commuting. I would also recommend this to groups who want to live local far from the buzz of Tokyo.
