It’s a little bit cramped when you have to go with larger people,but our driver/guide was very knowledgeable. He really knew the city. Unfortunately this tour brings into focus the homeless problem. We had heard that there was an excrement problem in the city, but during our 3 days going through all parts of the city we did not see any evidence at all.
This is a very complete tour and is quite worthwhile.

This was a great experience!! We visited three Sonoma wineries where the representatives chose excellent wines for us to sample and gave really in depth information. Dave, our driver, was exceptional! He was will informed and very entertaining. A huge plus - he waited with us for our Lyft driver (who was struggling) since we had a box of wine and other goodies. Highly recommend! Fun way to travel!!
