I wouldn't stay here again! The check in process had email instructions and no one there physically, I was told to ring a number and the door would open but when I did this the operator said the number was out of service, this threw me so I tried to ring the second number I had been given to be told this was out of service too! At one point I thought we had been conned and had nowhere to stay!!! Luckily another resident let us in. The apartment wasn't very clean, there was dust all over the fan, behind the bed cabinets and the bed, we also found several spiders, fake eyelashes and a used tissue next to an empty condom packet! There were cobwebs under a cupboard door, the shower fell off if you put the water on fast and the bath only had cold water from its tap. The white microwave was brown inside! My daughter always complained of itching when near the bed and as we left she came out in bites all over her body! Not sure if these were from inside or not. We only stayed one full day and as the number given was out of service it seemed futile in complaining at the time. I have since spoken via email to the owners and they have apologised and said they will speak to the cleaners! If visiting Vienna then do your research on the Zones before booking, this apartment was in Zone 10 and whilst it isn't the worst area for safety it isn't the best either and in the evening I felt quite vulnerable! As with all big Cities always have your wits about you and be mindful of pick pockets!
