We spent a week in this house (6 little kids) and really enjoyed our stay. The house has a great open layout with plenty of space. We didn't feel like we were on top of each other and we were able to feel comfortable and relax.
The house itself is clean, well taken care of, and has several fun amenities. Not only is the landscape in the front beautiful, the back yard has a covered patio with furniture, a putting green, and a small lap-style pool with hot tub. With kids, the pool is a must, and was heated throughout the day. The hot tub heated pretty quickly and we really enjoyed it at night as we wound down and relaxed. The putting grean was a nice amenity and something fun to do that we really enjoyed with the kids. The kitchen was clean and had all of the necessities to make a few meals. The garage was stocked with coolers, beach chairs, umbrellas, snorkel gear, beach toys and boogie boards, which make it very convenient. The outdoor shower was amazing and got really good use. The house is also stocked with many electronics and things, but we really didn't use them.
Marisa was easy to communicate with and quick to respond on things. We didn't have many issues, but any questions were promptly responded to.
The house is located close to several great beaches. We explored a bunch of them (I think 8 or so beaches and had a great time). It is located about 30 minutes from the airport, Walmart, or Costco. That is probably the one downside to this house. It is about 10 minutes from Waikoloa Village, which has a KTA (small grocery store) and a couple of restaraunts (Mexican, Thia, and Pizza), and about 7 minutes from a couple malls and larger resorts. Other than the mall and the few things at the Village, there weren't many shops or restaraunts, or at least we didn't feel there was a great selection. There were not fast food locations at all unless you drove about 30 minutes near the Walmart and Costco. Not that I love fast food, but with kids, sometimes it is nice to grab something quick. The only other thing was shopping. We found the best shops for us to be in Holualoa, but that is also a 50 minute drive.
Other than just some additional driving, it was a great place to stay and we really enjoyed it.
