My parents stayed in this apartment for 6 days and they were delighted. It corresponds perfectly to the pictures, the kitchen is well equipped, everything is working properly, and the place was super clean.
the location is pretty nice, calm neighborhood, really close to the metro going directly to the center and most of the touristic places in Vienna. Moreover, they are plenty of supermarkets and shops around if you want to stay a bit at home.
Last but not least, we did not had the chance to meet Aida, however her aunt and uncle are super friendly, nice and really willing to help if need some advice or so.
I highly recommend it.
