Great large flat space on the upper level of this house.
What we loved the most about this house are all the little things that came with it: plastic containers, films wraps, lots of spices and seasoning, beach towels and a lot of extra bath towels, beach toys and boogie boards... Having all these little things available made our stay easier and more enjoyable. The house also comes with enough beds + mattresses to sleep about 8 people (1 queen bed, 1 juniors, 1 sofa-bed and 1 futon mattress). We have a 2 year old toddler so we were quite happy to find the futon mattress and have a sleep on it near-ground.
The location is great. It's 2 minutes away from the village's grocery store (KTA), 10 minutes away from the highway (Queen Ka'ahumanu Hwy), about 20 min from Hapuna / Mauna Kea beaches, 45min from Kona, and 1h from Hilo.
One thing to know about Waikoloa Village is that it is often very windy (winds come from the East). But unless you want to play golf there, that shouldn't concern you. The house's balcony and grill are on the West side – which is great to watch the sunset – and shielded by the house's walls so you can enjoy nice dinners outside without being bothered by the wind.
We loved our stay here and we will definitely try to book this place again next time we plan to visit the Big Island.
