Overall had a smooth stay! It's nice to be closer to the Schonbrunn palace and all the sights there. Ample bedding in the house, and lots of little things that kids will appreciate (toys, a place to play under one of the beds). Also a nice kitchen setup with a pod espresso machine.
Had a small issue where the toilet smelled like urine. Also note that there is no wifi on the description - Johannes sent instructions for wifi before we arrived, but those did not end up working. So you will need to make sure you find some other access to wifi. There was a free wifi spot just around the corner from the apartment that we were able to use.
