We really loved our stay at Anna's studio! Anna and the local host were both very communicative and responsive to our questions.
Overall excellent value for the price, but keep in mind this IS a studio. Between the blender, microwave, toaster oven, and BBQ we were able to do a fair amount of meals on site - but you will be cleaning up using a small bathroom sink. That said, the kitchenette is very well stocked, clean, and has a full-size refrigerator.
Also note that the studio is an adjoining unit to the larger space next door. Sounds like you could rent both out and open the spaces up to each other, which would be fun for a larger group or family! We had some issues with neighbors' noise coming through the thin adjoining door, but nothing too bad. We were out exploring most of the time, anyway!
It really is a very comfortable space with tasteful decor, a large comfy bed, cute lanai with gorgeous landscaping right outside, and it is literally steps away from the pool and just a short (beautiful) walk to Kihei's best beach: Kamaole II. The studio has all the beach gear you need, and if you stay here you also get access to an incredibly useful local guide with tons of tips for exploring Kihei and the entire island of Maui.
If you're up for a slightly more modest space with all the luxuries of a bigger condo and excellent location, I highly recommend staying at Anna's studio at Maui Banyan! Mahalo!
