A fire at the Calistoga Inn on Lincoln Street around 3:14 a.m. Tuesday was quickly put out by more than 20 firefighters, according to city fire chief Steve Campbell.
The inn was "well involved" in flames when firefighters arrived, Campbell said.
Twelve hotel guests were relocated to the Christopher Inn and nobody was injured, he said.
It took 20 to 30 minutes to knock down the fire, but some firefighters remained at the scene more than six hours after knocking down the fire, Campbell said.
