The first impression at Nadi Downtown Backpackers is not exactly the best, and the really should improve the look of that reception. I stayed at a single bedroom with a/c, and I can't say the rate was cheap, but it's in accordance with the local average. The best thing about this hostel is the location, right on the main street.
Important to say: internet is not free, you can sit at their shared computers but once you spend 20 mins, someone comes to say you have to pay if you want to stay longer. Buy a local sim card from Digicel, if you have mobile modem and use your own laptop in your bedroom.
Free airport transfer is subject to how many people they will be taking. If you're on your own, they won't send a car there with just one passenger.
I would come back here, as the options are much worse.

This place is a -------- don't go here! There were bugs in the bathroom like cockroaches, spiders, flies... The bed was rock solid and the bathroom door didn't have a handle/lock. They gave us 1 towel for a 3 bed room. When we checked out at 5am to get the free airport shuttle we found the receptionist and the other lady who works there asleep in the office...strange.

i syay @ down town hotel very very good good good free brake fast free internet staff very help full you stay 3 night get you get i night free

The Nadi backpackers inn had a great commercial at the airport with free pickup service. We evaluated that a stay here on a simple double room was better than a cheap resort because of prices. On their "about us" section they seem ideal for a backpacker. They even had "free internet" and private rooms from 30$ or so, but we ended up paying 65$ because it was per person.
They say that they are an " ideal home base for travelers while exploring" and if you are looking to explore getting mugged or buy drugs on the dirty streets of Nadi, that is very true. One of the local drug-dealers came up to us right outside the hostel and offered us a taxi, drugs and he also gave us friendly advice how not to get robbed and he also told us that we had to pay at least 4x the value of prices on restaurants because we are white. Nadi is a one-street s***hole and the hostel is conveniently located right in the middle of it. The "free internet" was only valid for 10 minutes and with the slow speed they offered it would not be enough to write a bad review on tripadvisor without paying for at least one hour. They also charge a low but incredible detailed and annoying price of 5$ for one hour, 10$ for 6 hours and a few other complicated options depending if you wore using wireless or a plug and also it was something about where on the house you wanted to use it. The taped up Pool-table was a 2$ extra charge, breakfast was poor (two slices of white bread with some kind of horrible jam, a shot-glass of watery juice and a weak cup of tea or coffee....)

Our "luxury double room" needed a new layer of paint, a doorknob on the incredible small bathroom`s door, a fan that does not sound like an attack helicopter, soundproofing (it was like we wore partying with the neighbors when we wanted to sleep), some fire safe electrics work (not tape on wires) and a few towels, a TV AND WIRELESS SIGNALS! I hate to pay for internet and get confined to the reception area.

Once the boss figured out that I was going to write a review here he got all scared and tried to charm us in to writing something nice by giving us 40% off on the next stay and showed us plans on how the place will look like in a year or so. When he tried to show me hes great reviews here the first headline was "horrible place run away from it", haha! The boss himself is a nice guy, but and old Indian guy working there would constantly try to tell us how to spend our vacation and he tried to plan our days by booking things through him or he would lure in the corners behind us. It was kind of annoying that he was spying on us like a predator when we tried to find a decent place to stay.

But if you decide to go, make sure to read the tips about how to handle the con-men that is painted on the door who leads out to the streets.
