We would definitely stay at Nobu's place again. It was really cute, with a nice view and great access to facilities like a pool, hot tub, fitness centre (with a $5 registration fee). Nobu was very responsive and a great host! When our flight arrived an hour early, we were able to check in a little bit earlier which was amazing, because we didn't have to hang around for an hour with our luggage or pay $10 to have it stored with security. The location is great - within walking distance of both Waikiki beach and Ala Moana shopping centre. There is a Biki rental dock right outside the corner, which is convenient. It was also super helpful to have a small kitchenette in our room - the fridge/freezer, kettle and microwave worked well. The small induction cooktop doesn't seem to be working, but we didn't really need one.
The only cons to Nobu's place were that the curtains didn't seem to stretch over the entire window, just most of it, and the AC took a while to function well. There was a fire drill at about 11pm on our last night, but it was a false alarm (and not Nobu's fault). My boyfriend and I couldn't figure out how to turn on the shower at first - but a quick message to Nobu and he helped us out - you need to pull the switch out towards you. There are a few extra towels in the TV unit cupboard, but it would have been nice to have a floor towel for the bathroom.
