I understand that most rooms do not have windows. However, there was no system in place for proper air circulation. The air conditioner was set to 18 degrees Celsius, but it had no effect. The room was extremely hot. I requested a fan, but there was a very unpleasant odour. There was also no mobile phone service in the basement. I asked to be moved to the upper floor, and I was willing to pay for the accommodation. However, I was informed that the hotel was fully booked. Checking in was very slow, with only one person at the reception desk. Overall, the room was smelly and lacked proper air circulation.
