10th Anniversary – A Reason to Celebrate!
On May 4, 2016, we had the pleasure of welcoming our first guests—a moment that remains a cherished memory to this day. We are incredibly proud of what we have built together over the past ten years. We are especially delighted that some of our guests have been with us since 2016 and have remained loyal to us to this day. We are also filled with gratitude that familiar faces from our team have been part of Hotel K99 since the opening. It has been ten exciting years full of wonderful encounters, beautiful moments, and great dedication—and that is exactly what we want to celebrate with you! Our anniversary highlights:
🎂Open House on May 2, 2026
🎂 Anniversary barbecue on May 16, 2026
