If you're interested in visiting Vienna, I could not imagine a better place to stay. The apartment is a very short walk from the first district, which is full of activity, but in a quiet area that felt very nice and private. Public transportation is incredibly close by, giving easy access to the rest of the city. The hosts are very kind and helpful, leaving a plethora of tips about what to see and how to get there. I cannot recommend this apartment highly enough - really excellent.
