We had an excellent time at Yasuhiro's apartment; we felt like we were at home from the moment we walked in. Yasuhiro is clearly a very experienced host; he was quite prompt in responding to messages despite the time difference between Japan and the US and everything in the apartment was labeled and user-friendly.
The apartment itself was in close proximity to train lines, convenience/grocery stores, restaurants, and is nestled into an adorable little community that you really felt like you could be a part of. The apartment could probably fit between 3-4 adults comfortably and the amenities were thorough and easy to use. I would certainly look into staying with Yasuhiro again in a heartbeat if I was to return to Japan, thank you so much for your hospitality!
