Excellent location in the city center and clean! Lots of bars and restaurants and attractions all around. Easy access!
No windows to the streets which made it quiet but very noisy pigeons in the backyard type of space and no blackout curtains which made it difficult to sleep. I slept on the sofa bed which was ok but my friends weren’t quite happy with the quality of the bed. Don’t count much on the mini fridge. You should keep in mind that there is no AC here so check the weather.
We loved Vienna! Amazing city :)
