I've visited twice since Birmingham University opened it up. A truly splendid house - beautifully decorated and well appointed, featuring Arts and Crafts William Morris wallpaper and fabrics. The tea room and terrace is a particular delight, as is seeing the staff dressed in Edwardian costume. The gardens are of course lovely, and include an alpine and cacti house. A pathway which meanders through wooded thickets takes you to Edgbaston Pool, which is secluded and very beautiful.
Highly recommended!
