The apartment is super clean, stylish, and cosy. The beds were very comfortable and there was a kitchen stocked with all necessary equipment. The shower has about 70L of hot water which goes quickly so you can't really take more than 2 showers back to back. But it only takes about 20min to refill. It's about an 8min walk from the subway to go downtown or to the airport. Overall a really great stay for enjoying Austria.
