I stayed three nights with an 8 yo child and an 8 mo baby and the place worked so well for us.
The location is so good if you travel around by train and the centre of Vienna is so easy to get to.
A little kitchenette has all the crockery and equipment (microwave, toaster, freezer, nespresso machine). Everything is very efficient and thought through. The housekeeping and reception staff were very friendly and caring.
Thanks a lot
