Ed was a phenomenal guide, so knowledgeable. At first bothered by the price, but found it to be a great value. You just can’t see so much of the city on foot (and forget about doing by car). Make this your FIRST tour and then go from there. We needed no other tour. Got the history, geology, geography, socio-dynamics, and views of the city in 3.5 hours. Oh and the restaurant recommendations. One thing to get Yelps, another to get the Local’s. E-bikes made it easy to climb the hills. Again, make it your first tour and sus from there.
