She was called Mädi in the family and had a lifelong friendship with her cousin the Archduchess Marie Valerie of Austria.

As the climate in Sigmaringen was not suitable for her constitution, she lived mostly in Bad Tölz (in the summers) and Cannes (in the winters), and was treated to regular visits from her family.

[citation needed] According to her sister-in-law, the Queen of Romania, "Somehow, Mädi could not fit in with the Hohenzollern family; she seemed to actually take pleasure in shocking them whenever she could.and was extremely thin, with pale blue eyes and a pathetic voice.

Her health was not robust and she was quite an invalid, wheeled about in a chair, before she died at the age of 42… she saw very little of her children to whom she was a mother in name more than fact… Madi's one great love was her mother, Countess Trani, sister of Empress Elisabeth of Austria [...] poor Mädi [...] seldom crossed my path.
