Answer: ICEHOTEL

Icehotel is a unique hotel made entirely of ice and snow. It is located in Jukkasjärvi, Sweden and is rebuilt every year using around 5,000 tons of ice and 30,000 cubic meters of snow. Guests can enjoy sleeping in rooms made of ice, as well as various activities such as ice sculpting, dog sledding, and the mesmerizing Northern Lights. It is indeed a "chill" place to stay, both figuratively and literally, as the temperatures inside the hotel stay between -5 and -8 degrees Celsius (23 to 17 degrees Fahrenheit).
