^^You can go see for yourself, I think I remember those buildings being located at the corner of Bates and Boulevard of the Allies.
Its entirely possible to take the elevator to the top floor. There are some executive offices, but nobody bothered my friends and I when we went to the top to peer from the windows. There are also ledges on some of the intermediate floors that some have climbed through the window and sat on.
I've been waiting for someone to photo Juliet, the street I used to live on in the true South Oakland, which is technically that which is horribly sectioned off by the boulevard of the allies.
My house would've been directly to the right (edit: left i mean) of this photo but its so incredibly derelict, that I don't blame you not bothering with a picture.
