Staying at the Grand Ferdinand was a dream-like experience. I was thoroughly taken care of by kind and helpful staff from baggage drop to check-out. Everything was absolutely perfect. The location is 10/10, the room is bigger than it appears in the photos, and the amenities were amazing (the locker was big enough to store your luggage + hang your coats + has a lockbox, multiple towels, and also slippers!). Make sure to check out the Grand Etage for a breathtaking rooftop view and pool. Strongly recommend staying here – it will make your Vienna experience perfect :)
