We are an American family of four adults that really enjoyed staying in this house for ten days. It is extremely convenient to practically everything, including Tokyo & Shinagawa stations where you catch bullet trains. There are two great supermarkets; one caters to expatriates so you'll find lots of American staples you won't find elsewhere, with labels you can read.
The house is truly Japanese style, so if you want the feel of Japan, this is it. The neighborhood is very Japanese You'll walk down tiny little alleyways to reach it; some so narrow you'll need to collapse a large umbrella a little so it will fit through. There's no traffic noise because there's no way for cars to get near this house. The noise from the major boulevard completely disappears before it can reach the spot where this house is tucked away. Be sure your luggage is light or on wheels, as you'll walk about 200 meters from the closest place a taxi can drop you. We walked from the subway station a few minutes away with our luggage. The neighborhood is extremely quiet, so if you're looking for a place to party at night, don't stay here. Noise will carry to other houses. The neighbors are very respectful; very quiet as well. If your looking for a peaceful place to get a good night's sleep, this will suit you well.
The living room, though small, was a much better place to unwind after a day of sightseeing than just a hotel room. The kitchen gave us great start on the day with a morning snack and cup of coffee before heading out to see the sights. The combo washer / dryer was small like most Japanese appliances, but served a family of four adults well. It allowed us to pack fewer clothes. A tip from the landlord led us to dry clothes in the open air rather than in the dry cycle. That gave the clothes a fresh feeling we haven't felt in a long time.
We had everything we needed. It's a flow through water heater so no worries about running out of hot water. The beds were comfortable. (Note the low ceiling height in the attic bedroom. Our 22 year old, 6 foot tall son slept there just fine, but it might not suit all adults.)
Everything was in perfect working order. We didn't have to call the landlord once. The interior has lost of new finishes and was attractive.
