1. Great location
2. Excellent connectivity to city. There are two bus stops right outside the door which take you to the underground and schonbrunn palace and zoo.
3. Billa is around 300 mts from the place so you can buy all the groceries you need.
4. Its in a quite area as there are no next door restaurants or pubs.
5. If you are coming by car then plenty of street parking space i.e. paid between 09:00 to 19:00 and free in the nights but certainly no lack of space.
6. The check in process was easy and detailed so problems.
7. Even with only 1 room it is a big place with really high ceiling.
8. The bed and sofa bed are really big so no lack of space.
9. The bathroom and toilet are really big as well.
10. All basic stuff for cooking and cleaning was already available.
If you want a place near Schonbrunn then I would certainly recommend this place.
