Kateryna's place is definitely accurate and as described. Her communication was excellent and check in was easy and straightforward (her brother waited for us to arrive which was very appreciated). The place has pretty much all that you need and is very conveniently located near the public transit station. Very convenient to jump on the train across the street and head into the inner stadt.
Our one and only issue was the hot water for showering was quite limited but we were warned to wait 45 mins if using the hot water consecutively. Even then, I would say my girlfriend and I were limited to 3-4 minute showers each (even with waiting) before the water became quite cold. Just something to consider based on your needs, but we worked around it and were only there for a few nights so we made do.
There is a nearby Billa (grocery store) and a few restaurants in the area but we found it so convenient just to hop on the train over to the city centre where there are more options. All in all, this place was really good value for the price and we were happy with our stay here in Vienna.
Thanks!
