"This hotel is a refurbished former hotel inside a ruined convent of the Middle Ages. The refurbishment is fantastic. It preserves the ambience of an old castle with all the modern features. 2 outside pools with incredible views, one indoor pool with spa, a very good restaurant and kind and well trained staff. AC works well. WIFI is slow. We had a suite consisting of bedroom and living room of average size with a big bathroom including a sauna. Although everything very modern the decoration is cozy and pleasant. Being on top of a hill the views are stunning. Perfect base to explore nearby towns and the Dolomites valleys."

"Castel Badia is a newly renovated castle/former nunnery that is very unique, authentic, yet with modern amenities. We chose it for our trip also due to its location for exploring the dolomites. a perfect combination."

"⭐⭐⭐⭐⭐ A Fairytale Castle Experience We Will Never Forget Our family spent one night at Schloss Sonnenburg (Castel Badia) during our Italy journey, and it became one of the highlights of the entire trip. From the moment we arrived, we felt less like hotel guests and more like welcomed friends. The castle itself is stunning—rich with history, beautifully restored, and surrounded by breathtaking views of the South Tyrolean mountains. Every corner feels like stepping into another era. One of our favorite experiences was the walk from Castel Badia to the neighboring castle. The scenery, peaceful countryside, and timeless atmosphere made it feel like we were walking through a storybook. It was one of those rare travel moments that you’ll remember long after returning home. What truly makes Sonnenburg special, however, is its people. A heartfelt thank you to Adriane, Giada, Gabriella, Giusy, Cristian, and the entire team for their warmth, professionalism, and genuine hospitality throughout our stay. A special thank you to the bartender (my apologies for forgetting your name) for the amazing locally sourced and thoughtfully curated drinks. The cocktails and recommendations were exceptional and added so much to the overall experience. And an extra special shout-out to Cristian, whose dinner service was outstanding. His attentiveness, menu recommendations, local insights, and genuine care for our family made the evening feel truly special. He represents hospitality at its very best and played a major role in making our stay so memorable. The food was superb, the atmosphere was magical, and waking up in a centuries-old castle surrounded by mountains was an experience unlike any other. We have stayed in many luxury and boutique properties over the years, but very few combine authentic history, breathtaking surroundings, exceptional cuisine, and heartfelt hospitality as well as Schloss Sonnenburg. It is clear that everyone here takes pride in creating unforgettable experiences for their guests. Thank you for helping make Chris’s birthday celebration so special. We left with wonderful memories and a genuine desire to return. If you’re looking for an authentic South Tyrol experience that feels like living inside a fairytale, this is it. 10/10."
