We fell in love with this condo. We'd never been to the big island before, so we were surprised to see the Mars-like volcanic rock fields between the airport and the condo- however, the condo itself is in a beautiful complex, lush and gorgeous. We loved the location as it is was usually sunny and there is easy access to some of the best beaches in the world. However, as of now there are not that many services and restaurants nearby (and especially reasonably priced ones). More are planned, however! We packed lunches every day and ate dinner at the condo- it was much more affordable but you do have to plan ahead. It's nice because there were NO crowds when we were there except at OBISIC (the best shave ice on the island and worth the wait). We've heard that the other islands are teeming with tourists so we were so pleasantly surprised with how laid back, quiet, peaceful, and safe we felt in this complex and area. It was a dream.
The unit itself is great- this was the most well-stocked condo we have ever stayed at- it had EVERYTHING we needed for the beach. We did end up renting snorkeling gear but there are several sets at the unit. The unit was clean, spacious, and comfortable. We are a family of 5 so our son slept on the couch- as a 13 year old he was fine with it but an adult might not be as comfortable there.
The pool in the complex is lovely and great for kids- a max of 4' deep throughout. It's quiet and never crowded or loud. The whole complex is so peaceful and I love how comfortable I felt letting my kids walk around by themselves; it's very safe. There is a small fitness center that we were able to use when we wanted to get exercise out of the sun.
I would recommend Hapuna Beach for boogie boarding, Mauna Kea beach for wading and relaxing in perfect sand, and Mauna Lani (access comes with this unit) for a non-crowded great snorkeling beach. All three were perfect and so close! There is also relatively easy access to Hilo through the Saddle Road. We usually don't do repeat vacations but are already talking about going back soon- it was bliss. Enjoy!
