Location is great. Easy to do all you want on the island. Cold breakfast was not really worth it. Airco unit in the room was very noisy. Also, the way rooms are allocated is not very fair in our opinion, as you can get a pretty small room compared to others on the property - so beware and ask for a floor plan when booking. We did not really care about these caveats as we spent most time away. Book with them the Old Lahaina Luau, as you will get a better price. Also some other attractions might be worth booking through them, but we had our own plan. We did the Molokini snorkel with Paragon sail. Else we drove around the island, first the north part on the one lane roads and then around the part with Hana. The Paragon trip is better than others, as you never feel the crowd on the boat. Not really worth doing the turtles snorkel with other tours, as you find plenty of turtles around Little Makena beach.
Guesthouse provides beach towels and gear, as well as plenty of info. Things are safe as there is always someone there.
Wifi is also there.
