Nobu's apartment was really spacious, very comfortably fits 6 of us. The location was about 10-15 minutes walk for us from Ikebukuro, and there are plenty of convenient stores and supermarket around which was great for us!
However, the place does feel slightly old and the walls are a bit thin such that the sound proofing is a little poor. Also take note that the apartment is on the second floor but there didn't seem to be a elevator so you will have carry your luggages up the stairs.
Nobu was a good host as well, and as very responsive with his messages and even made the effort to check with me to see if we had any issues checking in. Thanks again!
