My wife and I went to Huahine, unplanned, this Spring. We hire a car at the airport and drove around looking for a place. We've stayed at multiple five star resorts but the initial appeal of this place tempted us. Also, the price was way less than Relais Mahana just down the road. We didn't want the isolation or price of the Te Tiare. Remember, you get what you pay for. The first night we were in a garden bungalow and then they gave us a free upgrade to a beach bungalow.
The food was excellent, although we didn't have breakfast which we thought a little over priced. We brought our own breads, yogurts etc elsewhere.
We loved the authentic charm and character of the gardens and bungalows. It was warm in the room but the breeze off the water was fine (remember, we didn't pay for AC).
Our complaints....... The thatch roof of the bungalow was not chemically treated (like at the big resorts) and whatever critters were living up there continually rained tiny poops on us. It was like sand on the bed sheets. I'd brush them clean but pretty soon the same again. The mosquito net doesn't have small enough mesh to keep this out.
Also, one night the 'waitress' gave us such atrocious service, you just cannot imagine. My wife wanted the lagoon fish with vanilla sauce. There was no lagoon fish available (huh! - in Polynesia) and when she picked a different fish dish they wouldn't put the sauce with it. Yes, I admit we do have a language barrier, but the service was the worst I have EVER experienced. The food that did come was very good, but we were the only ones in the restaurant and the waitress left and never came back. We were offered no desert, coffee, or anything else. She actually closed the kitchen and turned ALL the light off and left us in the dark. We even had to find our way back to our room in the dark! - Yes, I'm talking ALL the lights around the gardens, everywhere. (It was not a power outage because we had lights in our room.) Quite extraordinary.
Please keep in mind, that we are pretty easy going and have many friends we've made in Polynesia over the years. Contrast the waitress with some locals we met in Fare who took us by boat (the only access) to their little house by the lagoon for the day. They fed us, entertained us and showed the genuine and more common Tahitian hospitality.
We'll probably go back, the hotel charm was great, the food excellent and the cost reasonable. I guess we all have bad days, but that particular lady should NOT be waiting tables.

No air conditioning, the noise from the people in the room next to us made it sound like they were IN our room, the mosquito netting blocked any airflow from the ceiling fan, and the locals next door were noisy and invaded our privacy. horrible experience--not a wink of sleep and we left after one night. the hotel down the street was wonderful--go there instead

Meet with a major room upgrade, an incoherent manager, and a Cuba Libre composed 1/2 litre fruit, 1/2 litre rum, Pension Mauarii defined itself as the chilled alternative to 1000 dollar a night shacks on stilts who mix Robinson's lime juice in with a Margharita. Hell - the Mauarii might not know how to mix a cocktail but who in French Polynesia does? Vetea and the vahines were always charming, helpful when required, kept the restaurant open late and, in general, beat Relais Mahana and Te Tiare hands down in what you'd really want if you've made the decision to visit Huahine rather than Bora or Moorea. The beach and backdrop are absolutely stunning - just be wary of the Travis Bickle look-a-like with the axe in the vanilla plantation down the road. This is an unprecedented 'yes' vote. Oh, and the rooms are very cool - makes shabby chic look shabby. Wonderful co-guests (apart from les colonials).

Huahine is a nice island but not the place to stay longer than 3 days (we stayed 5).
Mauarii is more a hotel than a pension - lacks of privacy.
Restaurant serves good food but a bit overpriced for what you get.
The pension has one of the only beaches on Huahine Iti. For snorkeling just next to the hotel the best option, other areas where covered with sea slugs... Best for snorkeling is a motu.
No canvas chairs around, bicycle are actually for free but where not working as pedals where broken.
Canoes are a great way to get around - for free.
Hire a car in the pension is a good option to see the island but much better was the trip around the island by boat. Book the tour with the shop next to the pension.
Diving was a bad experience in Huahine hence the shop located next to the pension. If you are looking for big fish, loads of coloured fishes as promised by the owner do choose a different dive shop. The only thing you get is loads of promises not kept.
