The ninja house was exactly what we needed for our last week in Japan. It's great value for an entire apartment. It is a very close walk to the train station and in a great residential neighborhood but still just one train station away from modern Shinjuku and very close to Shibuya. The climbing took a little while to get used to but it didn't bother us at all once we got used to it. We also appreciated that we had a kitchen where we could cook our breakfast. The wifi was fast and reliable also. If we ever find our way back to Tokyo we'll be looking into the ninja house again.
