It's considered most likely she would go to the fed pen at Dunbury CT which is female and minimum security. She's free till her appeal is heard which the CTV lawyers said means at least a year. Anyway here's a story about what Danbury is like.

"Her living situation would depend on whether she is assigned to Danbury's barracks-style prison camp or traditional cellblock housing. Either way, the queen of fine living would find things very different at Danbury.
She would be ordered to turn over all belongings upon arrival. Wedding bands are allowed, although Stewart is divorced. She would be strip-searched.
"There's a guard. It's not too private. It's in this little alcove," said Joyce Ellwanger, 67, of Milwaukee, who served time last year for the same protest as Hartjes. "The guard will tell you to squat and cough. Your clothes will be sent home."
Stewart then would receive her room assignment.
"When you hear this door slam behind you, you walk into a place full of sadness, bitterness and emptiness," said Susan McDougal, who served time in several prisons though not Danbury for refusing to testify in the Whitewater investigation.
"She's going to spend the first part of her time realizing life pretty much is over. You're getting broken down," McDougal said. "You understand that you're on somebody else's schedule, somebody else is in charge and nothing is yours."
If there is room in the 200-person prison camp and her probation officer's report recommends it, Stewart would be sent there. If not, she would be sent either to a two-person cell or to a shared cubicle within a wide-open dormitory.
The walls are plain concrete and cannot be decorated. Inmates can personalize their space by hanging up to four photographs in their lockers. Stewart, who advises visitors to her Web site to search out bed linens with high thread counts, would not enjoy such luxuries"
She's tough, probably do a book. I feel sorry for her assistant who doesn't have her resources.
