I'm sorry to hear about the discomfort you experienced during your stay, particularly with the room being unbearably hot and a burnt smell from the ventilation. It's disappointing to learn that this issue was a known problem, and I understand how this impacted your overall experience. Your feedback is important, and I recommend reaching out to the hotel's customer service or management to express your concerns more directly. They may offer further insights, explanations, or potential solutions to address the issues you encountered. It's crucial for them to be aware of such experiences to make improvements and ensure a more comfortable stay for future guests. I hope your next accommodation will be more satisfactory, and thank you for sharing your experience.
