Seven of us stayed at Lu's place for 3 nights and it satisfied everything one could expect from an airbnb of this kind.
Lu was prompt with her messages and provided us with a guidebook to her apartment, including directions from local stations and instructions for appliances.
It was lovely to have dual toilets and showers with such a large group.
All living areas were clean and we enjoyed the traditional style tatami living area.
I would recommend this place to anyone looking to stay in Tokyo!
