We had a brilliant time at the Aloha Beach House. The house is charmingly decorated and easily large enough for a group such as ours - 6 adults and 3 kids. Great to have 3 bathrooms. And very convenient to have a fully stocked house with lots of beach gear, an amazing playroom, WIFI, etc. etc.
Daniel was very helpful.
Milolii is in the least touristy part of the Big Island, which suited as very well. The local beach (Honomolino) is nice, and it's also possible to swim and snorkel very near the house. But good to keep in mind that it's at least a 45 minute drive to any supermarkets, cafes, restaurants, white sand beaches, and golf courses, for people that are looking for a more resort-style Hawaii experience.
