Ahead of Wednesday night's solar eclipse, Jónsson compares the atmosphere at his fully booked hotel to a US-Soviet summit held in the Icelandic capital in 1986.
"I started the hotel then, and we had Reagan and Gorbachev here. It was very hectic," he told the AP news agency.
The meeting between heads of state Ronald Reagan and Mikhail Gorbachev went down in history as the beginning of the end of the Cold War.
The total solar eclipse over Spain and Iceland will be historic in other ways. For Reykjavik, it will be the first time since the summer of 1433, AP writes. And the next time the sun will be completely obscured by the moon over Iceland will be in June 2196.
