Takahashi-san is an excellent host who clearly cares about her guest having the best experience possible.
To be clear, you will have a single room with a bed, desk, and WiFi. You also have access to the adjacent kitchen, bathroom, and dining room meaning that you effectively have the entire second floor to yourself. Two train stations are a few minutes walk away and you're only about 10 or so minutes from Shibuya.
I wholeheartedly recommend this place for solo traveler's who want a bit more of a local experience.
