Really like this new type of dormitory room inside a fancy hotel that is well located (central). The beds are super comfy with nice sheets. The staff is cleaning the room every day (very clean) and provided new towels (set of 3) on a daily basis. The room included digital lockers. The plus is clearly the rooftop as well with the pool (that is quite small but so affordable for the price of the room). Really recommended if you plan to visit Vienna.
