Great value for Honolulu. Parking lot is definitely small, so get the smallest car you can. Ubers are pretty cheap though, so if you're going to Waikiki a lot you probably don't need a car.
The building is pretty old, so the electrical can't handle a lot of appliances at once but we didn't have any problems. The walls can be kind of thin though. We could hear the neighbor's TV pretty much all the time.
