We had a great time! The studio was clean and had everything we needed for a comfortable stay (large fridge, towels, plates, cutlery, etc). Was happy to see there's even a vacuum cleaner since we brought back lots of sand in our shoes.
Being caught up in traveling we were super late in informing Norman about our check in time, but he responded to our messages very quickly and was there to greet us at the apartment when we arrived. He gave us a lot of useful tips for places to eat and things to do in the area.
The building is in a superb location. Close to the beach and resorts. It's difficult to find free parking near the apt (or anywhere in Waikiki really), but you can park at the hotel for $25 for 24 hours if you show your keycard.
Would definitely stay here again!
