Great location in the middle of Waikiki, lots of things you can do by feet. The studio is cute, enough for 2 people.
Tip for parking if you're not afraid to walk 15mn : you can park along the zoo on Montserrat Ave, it's free street parking anytime,and you'll always find a spot (we were there during Christmas).
The big drawback of the studio is that it's extremely noisy: you'll hear everything from the street as the windows are thin and the a/c is just surrounded by a plastic board... So we didn't sleep a lot unfortunately.
Shannon is a great host however!
