Dorothea was super-nice and attentive! Gave very helpful advice on how to get to places in Vienna, treated me to breakfast on Sundays with her delicious homemade marmalade and even took me to a delightful traditional heuriger, which was a very nice experience.
The apartment is comfortable and clean. You can easily walk from there to the city center, but there are also bus, tram and U-bahn stops nearby.
