This has been my go-to hotel in Vienna for more than 10 years. It is a decent 4-star choice especially if you look for a peaceful stay in lovely green environment, a stunning view to the city, pleasing, classic architecture and opulent interior. The rooms are nice and spacious but nothing seems to have changed since my first visit, consequently the furnishing seems to be a bit aged and worn-out. The door of the bathroom is made of ground glass and you can see directly to the toilet from the anteroom. The hotel should definitely reconsider this choice. The sleeping quality could not be better. The beds are super comfy and the walls are so thick that you'll sleep like a baby even if a hyperactive kindergarten stays next door. I have a good general impression of the service, but the housekeeping did not excel this time. The breakfast is ok, the a-la-carte selection and quality is quite basic, but again, the environment is worth the price. You can enjoy your meal on the terrace, a cute winter garden or a luxurious ballroom with a breathtaking view to the city. You can get to the city center and the main sights in about half an hour by bus, it runs frequently (in every 10-15 minutes) and stops right in front of the hotel.
