The hotel has a central location, close to Karlsplatz metro station with a direct S8 link from the airport. The staff were efficient in dealing with my luggage locker request (2 euros, secure room in the basement, reached by a lift). Helpful was the grab-and-go breakfast and free coffee pods. The room was small but well equipped with wifi, hair dryer, TV. But my concern is the noise coming from the homeless vagrants who either sleep in doorways (including this hotel's) and the long-closed department store next door. This issue should be looked into by the hotel owners with the authorities.
