We stayed with 3 adults and a toddler. It was enough space for us to be comfortable. We have stayed in Maui before in a Marriott Hotel and I loved this experience more. It gave us the opportunity to walk around the town because everything is near by.
The parking is a bit tricky but we just paid for on sight parking to avoid trying to find parking.
The condo we VERY clean and came with everything you need. Highly recommend.
