Location wise this place was great as well as a great deal! Close to public transit so getting around Vienna was a snap. Also, we visiting an outdoor market 2 blocks away with an amazing bakery and display of fruit, vegetables, cheese, meat, etc. We felt very safe walking around.
Only had a few mild complaints, the fridge was broken when we arrived and took a few days to fix (host was very quick to respond though) so our plan to store food was a bit delayed, the bedroom had a slight chemical odor (might be from cleaning?) and the pillows were flat (might be a culture difference).
