Courtyard by Marriott St. Petersburg Center West/Pushkin Hotel

My friends and I stayed at Courtyard St. Petersburg Center West/Pushkin Hotel for a couple of nights for the first time and were rather disappointed with the service and would hardly recommend anyone to stay there. For more than a day hotel staff could not help us with fixing the temp in our rooms (+25 and +27 degrees C), their recommendations were useless and didn't work - they asked to change air conditioner settings to the desired temperature and wait, but nothing ever changed. Iterations ended up with them sending an engineer to the room at night, who explained in a pretty rude manner that it's winter and air conditioner would not work to reduce temperature but only to raise it - and no one would change these winter settings. Given the fact, our windows were facing some indoor place (reception and restaurant area, which was very noisy, by the way) opening them did not change the situation. The reception staff promised to find a solution and never got back to us. When we called them back they confirmed nothing can be done. Regardless of the fact that 25-27 degrees is heavily unhealthy room temperature, we expected staff to be more responsive and caring
