Wow, wow and wow.
Attention to detail in every way, cleanliness, directions, additional information to make your stay easy, courtesy, communication, comfortable bedding and bed, welcome drink, breakfast cereal, step by step instructions with photos.
Storage of luggage after your stay a great asset.
Great restaurants just steps away.
And if you came by car, I'm sure there would be a very easy well planned solution.
Recommend highly if you want a Viennese experience.
