It's not clear from the other reviews, but this isn't a standard YHA hostel. There are two parts - one bigger building next to the office, with dorm rooms housing people working on nearby farms, and a house up a side street with one dorm room and two double rooms for visitors. The latter is where you'll be staying if you're on a tourist trip. It's a regular house from Pemberton's logging days, which may sound quaint, but that means it has a tiny kitchen (a problem if there are more than a couple of people staying there), and high ceilings that keep it very cold.
There's basically no heat except for a wood stove, which is hard to justify firing up when you're only going to be in the kitchen or living room for an hour or two before getting in bed. The rooms have space heaters but they're not capable of increasing the temperature at all, given the size of the room, high ceiling, and drafty windows. It was pretty cold when I stayed there (down close to freezing at night, and only up to about 13C during the day), and that made me want to leave as soon as possible. The people at reception were hard to get hold of but helpful when they were around, and were able to give me a refund for the nights I had booked but decided not to stay.
It was clean, almost eerily so. Maybe they had a full change-out based on some of the other reviews, but it was completely spotless with what looked like brand new dishes and cookware in the kitchen (I was the only person there my first night). It was kind of creepy seeing that kind of stuff in what's supposed to be a backpacker hostel, where people often don't clean very well. They apparently have professional cleaners come every day to take care of the kitchen.
