Hale Wa'a is a nice little attached guest house. Although it is on the smaller side, it does have 2 stories, 2 bedrooms, and 2 baths. We had 5 people and it spaciously accommodated all of us. Quentin and his mom are great hosts and made us feel like a part of their family, even down to inviting us to meet their pets. If you're the type of traveler that likes to totally be left alone, this would be a downfall for you. Our group was all from Hawaii and we are all used to everyone feeling like family, so this was great for us.
The house was very clean, had cute little welcoming touches (Fruit bowl, fruit infused water, and Mac nut chocolates), and was very stylish with a theme. Hale Wa'a is in a residential area, but not far from the shopping mall (Kahala Mall), the trendy artsy hipster town (kaimuki-waialae), and the tourist Mecca (waikiki). Its nice to be outside of these busy areas, but close enough to see them. It also is very close to the beach, which is easily something you could do since Quentin has stocked the house with beach chairs, boogie boards, towels, and the like.
For the price, you can't beat Hale Wa'a with the amenities, location, and hospitality.
