I had a late arrival for a one night stay before an early flight out of Helsinki the next morning. I arrived in my room and was hit with heat. The thermostat was set at 28C. I tried to lower it. Several times. I was too exhausted to call the front desk to try to figure out how to cool down the room, so I opened the window (thankfully, it opened), took a shower, and plopped down on top of the bed. Otherwise, the bed was comfortable and the room adequate for my one-night needs.
