Hello, Guest! Thank you so much for leaving such a thoughtful review. While many guests appreciate the floor-to-ceiling windows offering the Han River view and the excellent natural light—the highlights of our accommodation—we realized through your feedback that we had carefully overlooked the fact that these features can actually cause sleep discomfort during the long summer days. This is something we wouldn't have known about without your mention, so thank you so much for sharing your valuable feedback. Based on your comments, we plan to immediately add a blackout curtain option for guests who are sensitive to sleep or prefer blackout curtains. We will welcome you back next time with a space where you can enjoy an even more comfortable and restful sleep. Please take care of your health during this hot summer, and we wish you nothing but good things!
