Koichi definitely deserves his superhost rating!
The apartment is exactly as described, and the pictures definitely representative of what you're gonna get. (It's Tokyo, so definitely smaller if you're coming from the US, but it never felt cramped). The place was clean, lots of extra linens / towels, and in a great location.
Koichi was an amazing host, picking us up at the train station, and even having some snacks available for us! Would definitely stay here again the next time I'm in Tokyo
