I loved that this property (one of the oldest buildings in Callander) is run by a youth co-op helping locals. What a fantastic initiative.
But what this means is that you don't have access to anyone during your stay. The email before arrival was easy - building and room access info.
Our only suggestions are PLEASE fix the extraction system in the kitchen. The entire downstairs stinks. Please provide paper towel in the kitchen and please add parking info (around the back) to arrival info. Otherwise, we found this hostel to be small and cosy, beds comfortable and hot shower. Everything we needed.
