We only had an overnight stay at Jenn's apartment but it offered everything we needed. The studio is small but fit two people (plus bags) and was clean. There was a decent amount of noise from the neighboring apartments as well as people chatting in the parking lot, but we were up early due to jet lag and it did not bother us terribly. The fridge and microwave both worked great; we did not try to use anything else in the kitchenette/closet area, or the pool area, and can't comment on those. Aside from that, the check in/out process was easy and straightforward and Jenn was quick to respond to messages and questions.
The best thing about the apartment was the location: <5 min walk to Kihei Kalama Village, where there are several lovely restaurants (Paia Fish Market and Kihei Cafe were both heavily recommended and were great with outdoor seating and sunset views) and shops across the street from a beach park with volleyball courts and public BBQs. There are also several shops just on the other side of the building, including a dive shop, surf shop, and grab n go.
