I had an out of town guest and needed a tour for a couple of hours. I found this lovely one where no reservation was required and the cost of $25 was reasonable. We all met by the red heart on the corner of Powell & Post at Union Square. We joined about 8 other lovely people who also would be on our adventure. Jay, our guide turned out to be a font of knowledge about the construction and periods of these lovely homes. Our tour mostly centered slightly north of Japantown walking towards Union/Pierce. We took the 45 bus west of Van Ness which was about a 15 minute ride max. First main stop was the Queen Anne Inn which is a B&B and I'm sure I'll recommend it to friends. I was highly impressed and will take other out of towners on this tour again!
