This may have easily been our favorite stay of our entire European Christmas Market trip.  Felt more like home or a bed and breakfast than a hotel.  Guesthouse is very appropriate.  Walking distance to just about everything and when it wasn't there was great public transportation or Uber.  Breakfast was amazing and they even had a honor system for cold drinks.  Coffee and tea always available.  Staff was among the most attentive and helpful, including the housekeeping staff.  Amazing.  I do have to include our main contact who welcomed us to the  property - Dina.  She was amazing, helpful, anticipatory, friendly and exactly the type of person you want interacting with guests.  We were even met with a 2 page list of dining options which got personalized for our stay by Dina - it was truly an amazing and wonderful experience.  Next time we are in Salzburg, there isn't even a question of where we will be staying.   Thank you to the owner, Constance whom met me at checkout, for providing a great house and staff.
