The Sound of Music brought me to Hotel Schloss Leopoldskron. If you are planning a Salzburg trip anytime soon, I would recommend staying here. I’ll just let the photos do the talking!
Staying in the Meierhof buidling is actually quite reasonable though there is the option to stay in a suite in the palace. I am a huge fan of the former, the room was modern, clean and just a 30 second walk to the palace. You must not miss the breakfasts!
