When we first arrived, we were underwhelmed. There was no one to help us with our bags, and after arriving in our room, there was urine still on the toilet seat.
The fire alarm also went off two nights in a row, which meant we were sitting outside in the cold, and only until right before the fire department arrived did they bring us blankets. It was utter chaos, and nobody was there to help us.
The breakfast was mediocre, considering the price of €90 for two people.
The hotel is in a great location, but for the price point, I recommend other five-star hotels located in the same area.
Overall, considering what I paid for the hotel, I am not happy with what I received. Next time I am in Vienna, I will stay elsewhere.
