I stayed here with my sister for a total of 6 nights in the Beachfront Villa, out of 10 nights in total in Fiji. We took the bus to Cuvu (which has some cheap supermarkets and an ANZ ATM) for about $5FJ each. The taxi to Namuka was $15, along a very dusty dirt road that takes you to the resort, which is in the middle of nowhere. From the resort, the closest shops are in Cuvu, which is a 1hr walk from Namuka. I would definitely recommend bringing some of your own food as the meal options are limited mostly to curries and frozen deep fried things at the resort. Bear in mind that there is no cutlery, jug or plates etc to make food in the rooms, so microwave meals are not always the best. I personally found the food quality here to be mixed - some was very good and some very bad. The fish, prawns and mussels come from frozen store bought packets; due to this the Mussel lolo dish gave me mild food poisoning and tasted awful, and the fish in the curry was thick and chewy from being frozen. There is also no dessert options so bring your own sweets unless you want to walk for 1hr to get an ice-cream! There are less fresh organic things here than we expected, and very little fruit and veg. I respect that the cyclone damaged some crops 5 months ago, but I feel that there is not much veg in general here as most supermarket food is processed and imported, not fresh, and the main export here is sugarcane.
The beach is lovely, but windy!!! Coming from Wellington, NZ's windy city, I can safely say that the wind here is bad. For the first 3 days it was too windy to comfortably sunbathe on the beach or lie in the hammocks on the lawn of the Villa's. The rest of the time at Namuka was calm, but being right on the south coast you should bear this in mind when visiting - I myself was not expecting this.
The lagoon is mostly shallow and full of corals so I wouldn't swim here without a snorkel or sand/beach shoes, as you are very likely to cut yourself on the coral. It was deepest in the morning and shallow in the afternoon, but you can walk around the beach to the right where there are better spots to swim, although it can be a long walk! When I say shallow I mean that you can walk to the edge of the lagoon only knee deep in water. One of the snorkels that I borrowed leaked, so I would recommend bringing your own. The snorkelling is super cool and a great thing to do at the resort without having to take a boat out, as it's right on the beach.
The staff were very lovely and friendly, though sometimes vague when asked a question. The owner visited sometimes, and was mostly heard yelling at someone on the phone, which I found unprofessional. The receptionist is great, but does the jobs of about 5 people as everyone else seems to be running on 'Fiji time', which is another way of saying lazy in this case. This meant that the receptionist wasn't always available when needed, and you could be waiting a long time for something small.
I gave the resort 3 stars in my review, as it really is a 3 star resort. Don't come here expecting 5 star treatment. Our first room had no hot water in the shower, and we had to be moved. There is wifi at a charge, but you can only use this outside reception or in the dining area, not in the rooms, which is very inconvenient and should be offered at the price you pay for the Villa. If you want to have a private conversation choose a quiet time of day as the dining area isn't very private. The single bed in the room was a foam mattress where you could feel the slats beneath it, but the big bed is okay. The rooms are nice and worth staying in, it usually pays off to spend more money on a room in Fiji, unless you're backpacking in dorms or something along that line. From my experience in Fiji, the general living standard is very low, for example people live in tiny tin houses with concrete blocks holding the roofs in place. This means that some cheaper places are in very bad shape. Don't trust pictures over reviews as it is very easy to take pictures of the beautiful things in Fiji without including the bad. If I was to do Fiji again I would stay on the outer islands, we met a couple who did the islands then came to Namuka, which is a good idea. I would also suggest to hire a car or scooters if you can, it will make getting around here easier and cheaper. Overall I liked Namuka, if more money was put into maintaining it the resort could be 4-5 star.
