While visiting my parents for the holidays in Honolulu, I stayed at Mike and Nicky's for 5 days and it was exactly what I had expected. It was in a perfect location (5-minute drive from Waikiki, 10-minute walk from ala moana mall and walmart, 1-minute walk from the convention center).
The studio wasn't so big but it had everything I needed including a hair dryer (because one of the guests had posted that it didn't have one before :), and an aroma therapy lamp for our comfort).
The studio front desk area people were very kind and polite and I felt very safe with my friend staying at the place. You can even cook in the studio (we didn't...) so it might be very convenient for family units.
Waikiki strip is close enough so we didn't spend much time in the studio but it was a great experience.
It was clean, convenient, and whenever I had a question, Mike responded promptly. I would love love love to stay at Mike and Nicky's place again!
Thank you for your hospitality! :)
