Carrie's guest host was a great location for city people--those who don't mind commuting around SF by transit. We preferred this, and chose the place based on that, and it was wonderful. The neighborhood is nice, away from the noise and chain restaurants of a downtown hotel area, and it's a quick walk a lot of major transit lines. We could easily reach all of the touristy areas, as well as connect to other residential areas of the city. There are some nice restaurants nearby, as well as a fabulous market. The only drawbacks to the guest house:

The steps down to the cottage are a little wonky. Fine for young folks like us, but if you have mobility issues and are unsure on your feet, please take that into consideration. There are a few concrete steps down, then some steeper wooden steps, a short pass, and then a few more wooden steps down to the cottage. I think the back light was out when we were there. Again, not a huge deal, but for older folks with lots of luggage this could have been cumbersome.

Also, the bathroom door. It was really one of those pocket doors versus an actual latching door, so if you're not comfy with your roomie hearing all of your business, take that into consideration! My husband loves his bathroom privacy (we're talking locking the door when no one else is home) so this made him a little nervy. But his quirks aside, this was a great place. Carrie made it clear that she was available, but didn't force herself on us, come knocking on our door, and let us enjoy our honeymoon. It was a wonderful trip! And the views from the property were stunning for us flat-lander Chicagoans.
