I didn't get to meet Kelly, but all in all it was an Ok place to stay. Check in instructions didn't work as described, but another person from the building let us in, and Kelly left the unit unlocked, so we managed to get inside anyway.
The bed is big enough for 2 if you don't need much space while sleeping. It is a studio, so you can't expect much room. However, the sheets keeps falling off the bed, and leaves you sleeping directly on the mattress.
Windows are always open and can't be closed, so you'll have mosquitoes inside the unit while sleeping.
Also, since Kelly accepts 2 people staying, it would've been nice if there were beach chairs for 2 and not just 1 person. If you don't mind a real budget stay, I would recommend you to stay here as you probably won't find much cheaper than this. However, for just a couple of dollars more per night, you get a better standard.
Location is fine, with walking distance to Waikiki. As mentioned, all in all, it's an Ok place to stay if you don't plan to spend any time at home.
