This unit at the Vista Waikoloa Condominiums is very spacious: large living room and master bedroom and a lot of balcony space. It has great views, quiet surroundings (although the complex was not too busy in mid July. Not sure how noisy it would be during high season), comfortable beds and the convenience of having washer/dryer inside the unit.
As previous travelers mentioned, the décor is a bit outdated and some of the appliances were probably not upgraded since it was built (~90's, I guess). In any case, we barely stayed inside so that didn't matter much. In addition they provided all we needed for a day at the beach, including a pair of beach umbrellas, backpack folding chairs, igloo ice chest, insulated tote bag, beach towels, boogie boards and even masks/snorkels (although we used our own).
My son loved the pool. We had friends staying at a more expensive condo nearby that didn't have such a large and nice pool. There's also an outdoor dining pavilion with 4 grills and several tables, just outside the pool area.
Unfortunately if you want to walk to the beach or to the nearby malls you have to go the long way, through the front gate. It would be very convenient if there was a path through the complex and adjacent golf course leading directly to the street.
Overall: nice place, good value. Totally worth it.
