Easy city to navigate, with many English-speaking people to answer questions. Subway, buses, trams require local currency, as do a number of shops (most shops will also accept euro, but not dollar). Do yourself a favor and stay an extra day, or two/three. Any more reputable guide-book will list many of the "Don't Miss" sights. However, one that is not well publicized, but note-worthy (in our opinion), is the Hospital-in-the-Hill. It is located in Castle District and was originally used as a hospital and later as an Nuclear Air Raid bunker, during the Cold War era. Contains many items of medical and radioactivity equpment(measurement/decontamination). Unfortunately, photography is not permitted inside the museum.
