This is a very roomy, clean, quiet apartment. It has a nice little kitchen, a comfortable bedroom (and a pull-out couch for more sleepers) and even a little deck, perfect for a morning coffee or an evening glass of wine. If you are an ambitious walker you can reach the 1st and 2nd districts without a problem - and public transportation is easy and close by as well.
Claudia, the host, was very quick to respond with any questions.
I would absolutely recommend this apartment to anyone traveling to Vienna.
