Nobu is an excellent host! She answers very quickly to all communication.
The apartment is very very well located. Walking distance from a metro station and from Shibuya, a very lively neighborhood (need to visit while in Tokyo). On top of that, the apartment is surrounded by embassies, hence it makes the neighborhood very safe. The apartment is clean and we had everything that we needed.
Nobu and her husband lives a few doors away so they can easily be reached.
I strongly recommend Nobu's place!!
