"Super well renovated guest house and excellent deal. This is luxury comfort when you are running experiments at the Advanced Photon Source. Breakfast is great too."

"Very friendly and helpful staff, clean rooms, and a convenient on-site restaurant make for a great stay when visiting ANL. Rooms are dated but clean with everything functioning fine. And you really can't beat the price point these days. Thanks for a great stay... again!"

"If working at the APS, the location literally can't be beat. Breakfast is just ok with a limited selection. You have to have a business need to access Argonne national lab to stay here."

"Probably better than any of the nearby hotels for Argonne. And less cost. Super convenient to the lab. If you can get a room, take it!"
