Eryn's condo was [mostly] a delight. It is nestled a few thousand feet up from the sea (enough that your ears will pop getting here), so while you will have to do some driving to get to the shore (Waikoloa Beach is 18 minutes away), it is also not nearly as hot when it's 95 degrees beachside. It is in that perfect zone between the always-sunny-but-sometimes-scorching beach and the cool-but-always-cloudy (if not pouring rain) inland areas above 3500 feet. Its location also makes exploring the wonderful north side of Hawaii a realistic option, something that's nearly impossible if you are in Kona or Hilo.
The neighborhood could not be more relaxing. There's a big golf course, very quiet even when busy, right outside (which we did not use for golfing, but rather stargazing at night - not quite as stunning as the observation facility at Mona Kea at 9,000 feet, but high and dark enough to see the Milky Way splayed out above you). The neighbors are also very quiet, except: one night a person in the condo above arrived at 3AM and we were kept awake for two hours by shoes walking and things being moved across the floor. I assume it was someone arriving on a very late flight, no issues any other night.
Tennis and great swimming pool are across the street and are included. Tip: the swimming pool is directly next to the courts, but you have to walk around both to the right and enter through the far side.
Now to be clear, this is in the middle of nowhere. The nearest population center is Waikaloa Beach*, and most of that is resorts; Kona is an hour away. But there is a (pretty terrible) restaurant at the golf house (confusingly known by two different names, but it's just one eatery), and a ten minute walk away is a small shopping center with both a KTA (a pretty big supermarket, much better selection and prices than the ABC in Waikoloa Beach and in fact the biggest and cheapest supermarket short of driving to SafeWay or Walmart in Kona) plus a slew of restaurants, including perhaps Foster's Kitchen (the best Italian place on the island but reasonably priced--if you skip the wine) and a food court with four takeout counters that look like something you'd find ten kilometers outside Tijuana...but the food is amazing! (If you have never had Filipino food, you will fall in love with Emma's Kitchen). Breakfast is at the coffee house located there (we preferred to just get something to take back, because if you eat in then you are required to use your phone to order and I still have a flip-phone :-); Emma's had breakfasts that sounded just amazing, but they don't open until 11AM. Avoid buying gas at the Texaco there as it is much more expensive than down on the highway (and the price of gas in Hawaii will give you sticker shock, so you really want to avoid getting into a situation where you have to gas up at that Texaco)
*Don't get confused when Googling "Waikoloa Village": this IS Waikoloa Village. Among other crimes against humanity (I'll be posting a rather negative review regarding that), Hilton Grand Vacations in Waikoloa >Beach< decided to call their resort Waikoloa >Village<...which is not where it is!
The condo is extremely well-equipped, including supplies and foodstuffs donated by prior guests (the next person staying there after this review will be inheriting the Big Wave Brown Ales we couldn't take with us). Here's a very helpful hint: do NOT stop and buy food or beach gear or washing supplies on the way in, wait until you are in the condo and take inventory of what is already there. I counted three bottles of mustard, four bottles of vinegar, and four shakers of salt, no doubt brought by renters who decided to stock up before seeing what the apartment already had. I mean this place was seriously stocked, both food-wise and equipment-wise.
Bed comfortable, but for us the "light-blocking curtains" just did not cut it; at 6:30AM the sunlight slices in horizontally and lights the condo up like a Christmas tree. If you don't mind the light, never mind. Within two hours when the sun has risen higher, the condo's interior darkens a bit with the blinds still drawn.
But with the rising sun comes heat, and the tiny portable A/C--no BTUs stated (I checked)--is unable to adequately cool the place if the outside temperature is above 90. Fortunately, thanks to the altitude that isn't very often. The A/C is also complicated to use. Speaking of complicated, we gave up on the myriad of remote controls for the various fans (we just left them on) and the entertainment system (I had brought along my own Fire TV stick and just used that; another hint is while Eryn's wireless network handles HDTV fine, it ins't fast enough to handle 4K so I had to go into my Fire settings and force 1080P, and then everything worked fine).
There is no dining room, but there's a small dining table with fold-up leaves in the corner and for meals we would move that to the middle of the main room in front of the television. You can also eat at the bar/kitchen island, but then you can't see the TV.
Special shout-out to host Eryn, who was pretty much instantaneous with responding to texted questions (where is the hairdryer, which towels are for the beach) and making the check-in/check-out process so simple. Mehalo!
