What a delightful little hotel! I truly felt like I was in Europe. The aesthetic was wonderful: quirky, comfy, and so, so welcoming. And as others have said, don't miss out on the strawberry crepes and really, really good coffee in the morning.
I was just passing through on my way back to LA from the Redwoods, but now I'm trying to figure out how to make Petaluma (and the Metro) a more intentional destination.
