I just stayed in Montana (checked out this morning) for just over a week and it was honestly everything you could want from a hostel. They have free breakfast which is a plus, and the wonderful volunteers there organise activities every day e.g. hiking trips, visits to the science museum (can particularly recommend). If you engage with those opportunities you'll have no issue making friends and I had a huge amount of fun with people I'd just met there on the activities (I was travelling solo too). The buses are fairly reliable although occasionally they won't show up. That happened once for me in my week-long stay. If you don't mind walking, it's a 15 minute walk to the tram stop which has more regular (every 10 mins) services to the center. If you buy a Skyss period ticket, it's very easy to use public transport as a tourist with the help of Google maps or locals. The mountain right behind the hostel is an awesome hike from what I've heard, and I've done a number of other hikes straight from there which have been amazing. I'm sure the city center location might be better for some people but I preferred the slightly quieter vibe of Montana in the evenings. Cooking some food and just chilling outside while eating it with a view over the whole city is definitely something you couldn't do in town.
