There is nothing negative to say! A spotlessly clean and comfortable apartment in a great location. It's bright and well furnished with everything you need, together with nice little extras such as potted plants, a coffee machine with coffee and tea provided. There are house slippers to wear - there's even a shoe horn and an umbrella!
As a bonus, the best pizza place in Vienna (maybe in the World) is right next door! There's a supermarket on the corner and nearby is the wonderful Augarten. In the other direction is the Donaukanal for walks, great cafes and nightlife ... and a fun way to walk into the heart of town. There is public transport all around - metro, buses and trams!
Perfect!
