For a family group of five adults it was the perfect option, the location was excellent for food and transport being in central Tokyo. The house is well set up four beds, three doubles and a single. The bathroom in winter was a delight in winter with the heating and instant hot water. Also set up to dry clothes, once we worked out how to use the washing machine. Two of the family are fluent in Japanese so that was an advantage.
The second floor living space with the large L couch worked well for us the large TV, great to view our trip photos and watch TV from our Mac in English, lucky we bought an HDMI cable. The kitchen was very well stocked but with the restaurants nearby we didn't do any cooking, but we could have.
Only suggestion was the double beds, not a queen they needed larger sheets. The pillows were very small but we all used one of the many couch cushions. We all sleep well, with air conditioning in every bedroom, great to heat up the rooms in December.
