Relocating for summer job

Looking for chill flatmate and ideally furnished room, I've got a summer job in Loch Lomond national park so will be commuting 5 days a week, not a massive social life, more likely to have a food potluck with a couple of friends and a movie night. Clean, tidy, good with houseplants and gardening! Cook simple food in bulk for cheap haha. I lived in Glasgow for Uni back when it was a lot cheaper so really looking for something as cheap as possible. Ideally looking for something close to a train station along the line to Balloch, currently in Partick and the commute is longer than I'd like.
