Niko's house has a modern and well-designed layout given the compact space that is common in all the Airbnbs we stayed at during this trip to Japan. The rooftop patio is excellent. I could imagine it being a cool hangout space in good weather (it was too cold for us during our stay). The house has some high tech and well-design appliances and furnitures. However, it would be helpful if some small amenities like hand soap were provided. The location is slightly inconvenient for elderly travelers because there's a 10-15 min walk to the nearest subway station (non-JR). It is, however, very near a Family Mart (small block away).
