Beautiful to explore on your own. Take the tram to the top, the view is amazing. Walk the wall in the morning, it's really hot at mid day. Again, amazing views outside the city but also into the courtyard gardens of the residents. There is a new disco (can't remember the name) near the fountain and it's super. Night jazz groups play at many bars so plan to do that too. See the oldest pharmacy (near the monastery) and sample the rose cream, it's better than Hauschka and Weleda!
fantastic of course
