Dear Guest Thank you for staying with us and for taking the time to express your thoughts and concerns. We are very sorry that your room was not at the correct temperature. There is a central air conditioning system in our hotel however each room also has individual settings. It seems there was a problem with your room. Normally the room temperature in the summer is 23 to 24 degrees inside the rooms. Regarding the smoke stack cross over the street, actually it is the condensed water from a cooling tower, this is harmless gas. As we are situated at the Dalian Sports Centre it is important for us to ensure we have a healthy environment. The outside air quality in our area is very good. Thanks for your comments on food portions. Our goal is to ensure guests are satisfied and we will make adjustments based on your comments. We hope you'd give us a chance in the future to show you improvements we are making, and look forward to welcoming you back to our hotel again. Please contact us if you need any other assistance. Thank you! Sincerely, Director of Marketing & Communications
