Avoid this hotel in warmer months. I understand that many hotels in Sweden lack AC, but this hotel has the worst ventilation system of any hotel I have ever stayed at. But worse, I kept being told by well meaning saff that although slow the ventilation system would bring room emperatures fown.FALSE! Even after changing rooms to an upgraded flat, the temperatures never came below 26.1 and sometimes climbed to 28 plus. But worse than that, the windows did not open and the rooms smelled musty, mildewy and sweaty. The result was several nights of interrupted sleep waking up in total sweat. Even after introducing two small noisy fans, i was still drenched during the night. Just horrible.
