We could definitely recommend this place. It has a beautiful garden, good coffee, a well-equipped kitchen and a nice atmosphere. We could also use the bikes of the host to cycle to the city centre (it's about 40 minutes to cycle to the centre, which gives you the opportunity to also see many other sides of Wien outside the touristic area). The neighborhood of the apartment is calm and safe, it has many shops and a few good restaurants (we could recommend the Asian restaurant).
