Spotlessly clean and very comfortable. We stayed here with our 2-year-old and it was a good size and had everything we needed for travelling with a kid, including blacked-out windows in one bedroom (awesome for naps). The kitchen and bathroom were roomy for a Japanese house and set up with everything we needed. Simple and stylish decor, it was a peaceful place to return to each day. The location is a bit inconvenient as there is only one train line and you need to change trains a few times to get to other parts of Tokyo, but since it wasn't our first time in the city we didn't mind being a bit out of the way. The neighbourhood has everything you need and a nice old-school vibe. Overall, we highly recommend this place!
