Weekend plans? (Stuttgart)

Hi people.

I has been assigned to Stuttgart for this and next weeks, therefore I am staying here during the weekend and hence I never been in Stuttgart previously - everything is new for me.
Can you kindly suggest, recommend or simply enjoy this weekend with me?
My current "residence" is Motel One (Heilbronner Straße) and from there either taxi or walking - depending on your suggestions.

Appreciate your posts :)
