Great place right off the U1 Schwedenplatz stop. Next to a number of great places to eat and drink (and live music at Jazzland), airport bus, and walk to the main cathedral Stephansdom. If you're new to Vienna be ready, as your check in will include a walking tour of the city :). Bryan has great recommendations of sights and food, and is very open to helping you get what you need or help out. More of a concierge than just a host!
