The house is clean and comfortable. We love it!
Sei is very nice and responsive. There were time where we had trouble with the internet, then Sei settle it quickly. She also provide lots of information for the guest such as location to the house from train station, convenient store location, public bath location and tourist spots around Tokyo.
Everything is OK for the house accept the door is a bit noisy and no so smooth to open.
We had a very wonderful time there and will come again!
