The location is perfect to reach the major sighseeings by foot or public transport (Vienna has an extremly good public transport, try it!). The flat was very clean, nicely decorated and it comes with very comfy beds. The host (Raphael) was very helpful and explained us everything, including some great tips for getting around in Vienna. He was also flexible for our late check out request.
We were 5 adults and only 1 bathroom was sometimes not easy. But on holiday we were not in rush to get ready, so it worked out at the end.
Thank you so much. Regards from Zurich.
