Excellent location, especially with children. Away from the bustle of right downtown, but only 10-15 minutes to everything. Underground subway, tram, and bus right across the street (but the windows were great -you couldn’t hear anything!). McDonald’s across the street and a lovely gelato place right downstairs. Something I didn’t realize about Vienna is almost everything is closed on Sunday’s (even in Stephensplatz) and grocery stores close around 730pm!
