I had an amazing stay in Koenji and Hiros apartment. Hiro is a great host! Social, respectful and helpful, Hiro was always giving some tips or interesting information about the areas that I was visiting. The room with the tatami carpets was clean and quiet - something you really appreciate after a busy day in Tokyo. Koenji is more relaxed and walking-friendly compared to most of neighborhoods I visited in Tokyo
I can highly recommend staying in Hiros house during you trip to Tokyo!
