Really nice apartment, it is just as it looks in the pictures. It is renovated and very well-equipped (Smart TV, washing machine, kitchenware, dishwasher, fridge, microwave, fan...). I found it very clean and organized, and the check-in was super easy. It is located in a very quiet neighbourhood and surrounded by all the services you may need (supermarkets, pharmacy, restaurants...), including the U1 metro line (ideal for visiting Vienna).
Also, Kaylee and Christoph are very attentive and professional.
In conclusion, highly recommended apartment.
