I am a businessman working in Tokyo. I have been assigned to Tokyo branch since Jan. 2012. All my family members are living in an area 2 hours away with airplane. Even though I am alone in Tokyo, I rent a pretty big apartment with 3 rooms which is in the center of Tokyo. My family members visit Tokyo once or twice a year. I thought it is waste of resource to stay at the big apartment by myself. That's why I listed my apartment on Airbnb.
I basically provide the entire apartment. Only when you want to share rooms with me, I will stay at the room. In the case, I can give you travel tips. You can freely choose whether you use the entire apartment or share rooms with me.
Thank you for reading. Don't hesitate to ask me whenever you have any question.
