"Turning a prison into a luxury hotel is no small task. It helps that Offenburg’s former penal institution, which comprises a pair of simple but elegant brick buildings that date back to the mid-19th century, was somewhat aesthetically pleasing — and it’s essential, too, that the hotel’s designers were interested in preserving some of the prison’s character instead of completely overhauling the place. After careful planning and renovations, the sleek Hotel Liberty opened in 2017." - Tablet Hotels
