I visited Berlin once again on our way back to western Germany. It was nice and we did a few cool things and learned a bit. My touristy pictures are from the Reichstag dome, Neue Synagogue, Berlin Cathedral, and Brandenburg gate.
We enjoyed lots of classical music, Gothic and Baroque architecture, and extreme heat (ha!) in Vienna. However, the city didn't quite have Budapest's charm as it was very touristy and rather expensive.
