The House:
The best part about this house is it has 2 showers, 2 toilets, & 2 bathroom sinks. It really saved us a lot of time! Both toilets had bidets, for those particular with this. 2 hairdryers. :) The kitchen is big and it had everything we needed. The blankets were comfy. They have plenty of clothes hangers. No need to bring extension cords. I think they have 2.
The Location:
The house is just a few minutes walk from the Nakai train station. If you have big luggage, take the A2 exit going down to avoid carrying your luggage. There is no escalator going down from A1. The neighborhood was very quiet. The place is close to a supermarket! That came in handy when we needed stuff for breakfast and dinner. There are also a few restos in the area. We ate lunch at the nearby Karaage place for lunch. It was good and reasonable priced! We also ate at McDonald's for breakfast on our way back to the airport. That was convenient. :)
The Host:
Yasuhiro was quick to respond to our questions. He even let us borrow a pocket wifi! That was very kind of him.
Overall, I'd recommend his place. We had memorable family trip in Tokyo, and we're looking forward to our next trip! Thank you, Yasuhiro! :)
