We've been vacationing on the Big Island for a long time. Location at Waikoloa is really spectacular, Nichol's condo is centrally located and very private and peaceful. Only downside is the place is very dated, not dirty as some reviews have said, just a bit dated.
It's a great value, our other option was in Waikoloa Village which was an updated one bedroom for the same price as Nichole's 2 bedroom. Waikoloa Village is a good 15-20 minutes from this location which is just a few minutes drive or a 10-15 minute walk to the beach.
