I spent two weeks on Fiji, travelling to Nananu-i-ra, Navala village and the Yasavas. Although I had a great time at all three places, the away-from-the-crowds Bulavou Beach Bungalows were definitely my favourite:
The apartments are modern, clean and nicely designed at 3-4 star level; they serve very good Fijan food, or your own catch-of-the-day and, most important, the owner Godfrey and his team really care about the well-being of their guests. The only disadvantage is that the resort did not get any more sun from 4pm onwards, but on the other hand, you can change to the sunny side within 10 minutes walking time and have beautiful sunrises alternatively.
Although chosen as "best pick" by Lonely Planet, I was positively surprised that the tourist crowds from the southern islands did not make it up here and you can "share" a 500m beach with just 3 people. For 150F$ per apartment (incl. snorkling and sea kayaks, excl. meal plan), there are cheaper ones around, but hardly any better for comfort and value-for-money. Hopefully, I can make it back again here one day.
P.S.: And for real Fiji village experience: Also go to Navala in the mountains... it's like a travel in time.
