"When I came down, the lobby was covered in thick, black smoke.
"It looked like there was smoke coming from the cafe. I didn't see anything on our floor, but when we came out of the apartment, we could smell the smoke. It was like a burning tyre or burnt plastic kind of smell.''
Guests at the Heritage Hotel across the road were also evacuated as a precaution.
A staff member at Marbecks Cafe, Manon Dupin, said staff were alerted by a member of the public who started tooting her car horn and then knocking on their shop door; showing them the smoke above their building.
Ms Dupin said: "You coudn't see the street. It was thick smoke.''
