This hotel has not gotten the memo about behaving like a low-cost airline and it is so good for it!
The building is ancient and centrally located right behind the Stephansdom. They stand out by a beautiful glass-covered inner courtyard inbetween the 4 sides of the hotel.
I got a classical room. One gets the impression of following history as they have exhibited famous signatures from their guestbook on the walls.
The room was extremely spacious, with a huge bed, two desks, even paper and postcards! Coffee / tea, as well as a minibar were in the room. Little attentions like a shoe-polish glove and chocolate on the pillow made the experience sweet.
The bathroom was very modern and perfectly fitted for all ages (including his-her sinks, chair, bathtub with shower glass etc), and with proper (local, own-brand, partly hand-made) toiletries.
Breakfast is also classical: cold options (sandwich and muesli mostly, and juices) are self-serve. Hot dishes (and they have about ten, including omelette and goulash; as well as coffee -tea) are made to order (included in price). The staff is super-friendly and pro-actively invites you to order the warm dishes.
All in all, I did not think that after living in Vienna many years there was still such a gem to discover. I will return!
