We had a wonderful time in Vienna with our two children.
The flat is spacious, surrounded by greenery, the house is quiet.
It is easy to park in the street and the tram station is very close (about 20/25 minutes to reach the city center with Nr 37 till Schottentor, depending on the traffic). Easy access is a really, really good point ! We thought that is was more difficult...
Equipments are top and modern (Wi-fi works good, TV with a lot of channels, washer and dryer close to the door of the flat, user manual can be found in the kitchen), everything is clean. There is a file with informations about transports, leisure, parks and gardens, restaurants... precious help.
We would come back there with great pleasure !
