We went through Vienna twice on this trip and stayed at Rebecca’s Airbnb both times. She is very on top of making sure you receive the check in information and was super flexible with us on check out so we really appreciated it.
The flat/apartment is on the first floor and right before trash days, the smell is in the stairway and hallway but usually fine in the apartment. The main bedroom is small and cozy but my husband and I are used to more spacious room so we ended up sleeping in the living room on the couch - super comfy and can extend too.
Overall, conveniently located - close to some grocery stores and a yummy coffee shop. Also very close to the U.
