I stayed here for a few days in December because there were things I wanted to see and do in the southern half of the island before heading north to Hapuna Beach / Mauna Kea. I picked Holua Resort because of its great price and location. One unique aspect of this resort is that you CANNOT drive your car up to your unit -- there is a large underground parking garage near the main office, and a staff member drives you in a golf cart to your unit. It's not a long walk to any unit unless you are trying to drag luggage or beach gear. There are pros and cons to that arrangement -- it is nice because the grounds are not chopped up by roads and car traffic, but there is an obvious convenience factor to consider, particularly if you don't walk so well anymore.
The grounds are nicely planted and pleasant, but the units are rather close together, and most of the balconies face the other buildings -- if your neighbors are out, you will know it. One side of a few of the buildings look out over the adjoining golf course, and a couple even have distant ocean views, but there are very few of these. Make sure you ask for and are guaranteed one of these if you really want that. The buildings are multi-unit octagonal structures with a small central court, a nice layout. But the buildings are older and wood frame, not brick / concrete, so noise from your neighbors can be an issue. They are nicely kept up on the outside, but all of the a/c units are located right along the building's wall on the ground floor rather than away from the building as they are in more modern developments. If you are on the ground floor, as I was, this is a noisy arrangement, particularly at night -- you listen to everyone else's a/c firing up. Don't even bother sitting on the lanai.
The living areas have recently been redecorated in bright, tropical colors (the designer must have been very brave!), but the kitchens are badly dated, although very functional galley style. The cupboards are kind of gross, the countertops are 4x4 white ceramic tiles with discolored grout in places. The appliances were certainly newer, but white rather than the stainless or black you might expect in a more upscale resort, and you could see that someone had taken a sawz-all to hack through the countertop to fit the new stove in -- not a very professional installation. The kitchen worked just fine and was reasonably clean, but no one would call it upscale -- more like what you would have in your rental unit. Bathrooms were fine, but again nothing special.
There is no beach access here. There are several small pools and hot tubs scattered around the property, about the size of a large backyard pool, and I never found them very busy. The biggest activity at this resort appears to be tennis -- there were at least 12 courts, not heavily used, so if tennis is your thing, this is the place for you. And there is a very nice golf course right next door.
In summary, this was a pleasant, inexpensive place to stay, but I would not rush back here. I certainly would never stay more than a few days, using it as a layover between other stops.
