As far as location and comfort go, Koanui is one of the top hostels in Blenheim. It's a BBH (budget backpacker hostel) member so its standards are pretty high. The rooms are clean and neat, and the kitchen is pretty well stocked. The main "living room" has a large TV with SKY and a wide selection of videos and DVDS to choose from. It's a pretty quiet hostel based on the fact that it's mainly a workers hostel. If you are in the area to fruit pick or do vineyard work this is a top place to stay. They do have contacts and can arrange to find you work (proper working visa necessary, of course). The main house is where you'll find most of the working backpackers. There is a second complex (the "lodge") with its own kitchen and lounge/TV room, this seems to be where they put most of travelers just passing through.Our double room had a sink and a TV in the room. It was pretty small but then again what more do you really need in the room? It had a chest of drawers and a cupboard and linen. However for the dorm rooms you will need your own linen or to hire some for $2.
Highlights of the hostel are the free pool table, barbecue, and laundry facilities complete with dryers. There are a few car park spaces in the back and off street parking is also free. There are two computers hooked up to the Internet but it's expensive and slow and you are better off trying an Internet place in town. The grocery store is only a 5 minute walk and town is about 10 minutes. The largest dorm style room is 6 beds and I never really noticed a line for the showers, they do have quite a few around. They owners are pretty friendly and they give discounted rates to those staying weekly. You'll get $2 to $5 off the price if you are BBH card carrying member. (and they are pretty strict about showing your card for the discount)
Dorm beds run about $20-22. Singles- $45, doubles- $50 and en suite-$62.
