The house sits in a typical Japanese neighborhood where you can feel the real life of a small local community. The house is lovely...three well prepared bedrooms with two baths. There is a nice supermarket (Union) across the main road...plus 7-11 etc. It took us about 10 minutes to get the edge of the bubbling Shinjuku commercial area...with countless number of stores and restaurants. During our stay of four nights, we did not go farther than Shinjuku (of course, it was our 8-9th time in Tokyo). We just wanted to relax and eat. Should you need to visit other places in Tokyo, the Shinjuku subway station offers almost all lines you would need.
The house was super clean. The breakfast area was well stocked with coffee, tea, jam, cereal, crackers, etc.
There is a washer/dryer combo which made the stay much more convenient than in a hotel.
Mizuki-san was super nice...when she learned that we only have three people, she offered to pick us up/to drop us off at the Shinjuku station with her small wagon. Because we had large suitcases, we could not fit in her car. But her warm gesture was certainly appreciated by us.
