Hotel
We would recommend The AC hotel as we have stayed there many times and really enjoyed the property and location. The AC is located in Railroad Square and walking distance to many restaurants, coffee shops and various stores.
Flight
Sonoma County Airport is approximately 15 minute drive to downtown Santa Rosa. It's a great small airport!
Flight
The drive from the San Francisco Airport to Santa Rosa is approximately an hour and fifteen minute drive (with no traffic). There is a toll to cross the Golden Gate bridge, but its a fun drive with beautiful views!
