Bigger than expected from the pics. We live in Honolulu and were just getting away for the night, so I didn't get to use too all of the great extras like the impressively stocked kitchenette, but I'd highly recommend for a longer stay. Towels were big and soft and plenty of room to put your toiletries. Might not be ideal in the summer if you're a couple that requires a king size bed or very cold temp to sleep, but we were very comfortable with the soft sheets and clean fans going. We didn't ask about borrowing their bikes (not offered, but I'm sure she would have obliged if I wasn't too awkward to ask:)), but enjoyed a nice long walk along the path in the morning. It was nice to see some of our favorite beaches before the crowds flooded in. Also super close to a beach access point where we went out for sunset and had the beach almost entirely to ourselves. Safe enough that we stayed out to watch the stars for quite awhile. They had automatic lights that ensured we safely got to our room when we returned (which is great for a klutz with poor night vision like me:)). Lanai others mentioned having coffee on is much bigger than I'd imagined. Perhaps that's because my own is only 2.5ft deep, but Silvia's is covered and big enough for four people to sit with a view of a charming, well-kept, little yard with the mountains in the background.
Price for one night wasn't too much cheaper than Kama'aina rates at Turtle Bay for one night, but a great place to really get away for a night, and even better for a longer stay.
Mahalo Silvia!!
