Considering the Hostel Adler in Berlin?

Unter den Linden - Festungsgraben Palace by yooperprof
Just off Unter den Linden, a bit behind the Neue Wache, the "Palais am Festungsgraben" is a dignified 18th century town house. Inside is a handsome marble concert hall, and the popular Tadjik Teahouse. (I had hoped to go to the Teahouse, but it didn't fit in with my schedule on this trip. Maybe next time.)
