David's place, whilst not as perfect as the pictures look, is immensely convenient for most travelers in Tokyo. I loved the location of the house, and David is a great host, with prompt communication. He's helped us to arrange transport to the airport at a much more reasonable rate than most companies would offer.
On the house, it was a little tight for 6 adults and 4 children. The place do not have a lot of free room to roam around, but it was sufficient. Also the configuration of the rooms make it a little hard to arrange our family's bedding arrangements, with an odd 5,3,2 on arrival. We reconfigured it to 4,4,2, and David was great help in helping us with better bedding for those sleeping on the futons, as the initial provided futons were a little thin and a little hard on the back, especially for the older folks in my party.
The amenities were as expected, and we had no issues using the dryer, washing machine, sink, heater, air conditioning. The house had a lot of modifications done, generally the adding in of what seem like either light or motion sensors, which makes it feel a little unsafe. Also we experienced power cuts a couple of times when two showers, plus the washing machine was in use, or when the kettle, washing machine and shower was in use.
The general cleanliness of the place is also not as expected, but still servicable. We experienced a toilet clog, which we cleaned up ourselves after removing a drain net full of hair, and a waste disposal cupboard that emitted a foul smell whenever we opened it up. The waste disposal cupboard, whilst a good idea, had food waste liquids seeped into the wood.
The rooms were for the most part clean, with dust in the corners, but not that bad.
Lastly, the pots and pans, whilst looking servicable, were of dubious cleanliness, and we opted not to cook primarily because of that.
