We arrived several hours before check in and my friend was feeling poorly--motion sickness from the flight. We were allowed to sit in one of the work spaces so she could lie down. In less than 15 minutes, the staff made a room ready for us and moved us right in.
A few hours of rest later, we walked out of the hotel and around the corner was the Opera House! And another block, the Albertina. Every site we wanted to see was within easy walking distance. The only time we even took the public transit was to ride the tram around the Ringstrasse, and the stop for that was right around the corner.
Breakfast was great, the room beautiful and the bathroom even had a double sink--so rare in Europe. Such a value for such quality and location.
