Koura lodge is a great value for travelers needing a place to stay in Queenstown. It is not in the city center, but between a 5-10 min drive from it.
Although there is a bus stop close by, the buses will only stop at that location during rush hours. Otherwise the next closest bus stop is a half mile steep uphill walk (which was about a 30 min walk for us). We wish we had known this, as we did not rent a car.
The lodge is pretty clean but there will most likely be other guests, as there are 6 guest rooms sharing the same shower and bathroom. We were kept up every night and woken up every morning by the other guests' noises nextdoor, but it will also depend on how courteous the other guests are.
If you will be renting a car and are on a tight budget, we highly recommend this place. If without a car, we recommend staying in the city center.
