Carla's place is lovely, well-appointed, and well-located for exploring the incredible north end of the island. Carla was very friendly and accommodating, and she was a great communicator throughout the process. She even gave us an extremely generous late, late checkout when we told her we were leaving on a red-eye on our last day.
I was a bit worried about the lack of AC, but it was not a problem at all. The fans and evening breeze combined to make a very comfortable sleeping environment for us (even though I tend to be hot at night). The apartment as a whole is very thoughtfully planned, easy to access, and has nice touches. The pool and hot tub were great, too, with great views of swaying palm trees.
For a longer stay, the lack of a full kitchen would be a challenge, but this was great for our two nights in Princeville.
