In Vienna, my husband and I stayed in a 7th floor apartment overlooking Stephan Platz, the square surrounding St. Stephan's Basilica. Our view of the basilica was right up against the cathedral through floor to ceiling windows and was stunning! The Sacher brothers were without doubt the most attentive and caring (without being intrusive) hosts we have ever had. They insisted on carrying our luggage when we arrived and when we left. The apartment is well and comfortably furnished, with washer and cable TV. For history buffs this is known Kennedy building where Kennedy and Khrushchev met right after the Cuban Missile crisis in the 1960s. This is a great location for walking and reaching public transportation that will take you all over Vienna, great shopping and restaurants are within walking distance.
The apartment was cozy and comfortable and very well maintained and this is the best area from which to see the historic sights. Plus there is convenient parking nearby.
