This is a lovely, nicely decorated studio in an excellent location in Waikiki, within walkable distance to both Ala Moana Beach Park/Shopping Mall and Waikiki Beach. It is the size of a hotel room but it offers a great number of amenities such as a fully-equipped kitchenette that accomodates casual cooking, a bath, work desk and chairs, and spectacular views. I stayed here for an entire two months and had a good time. The bed was comfortable, I cooked everyday in the kitchenette, and the wifi was good enough for casual Netflix streaming, though a bit laggy on video chats. Nobu's hospitality was excellent, he responded quickly to my inquiries and were able to provide timely help and solutions. The only thing I would note of is that this studio is near a high traffic road and has a loud AC unit, so there may be a bit of noise at night but it was not a big issue for me.
I would definitely recommend Nobu's place to solo travelers or couples taking a vacation in Waikiki. It is excellent for its value and amenities.
