As usual, I like what John King has to say here, about the building as well as the rest of the neighborhood. SF tries too hard to be a monument to the past, so it's nice to see a building that successfully tries to do something new and exciting.
We actually looked at one of the model units in the building back when they were still building it. Very nice. If we were looking to trade up, I think we might have thought seriously about it. It would be nice to live in a building with some common space -- the units here are all very separate, so there's not much community.
