Considering the Hotel Watthalden in Karlsruhe?
A VT member wrote the following comment about visiting Karlsruhe:
Marktplatz. by Maurizioago
On Marktplatz (Market square) you can see the town hall, the Evangelical church and a small pyramid. This is the grave of the city's founder; Karl III Wilheim, Margrave of Baden Durlach.
When I was in Karlsruhe, almost every day there were lots of flowers stalls in this square.
