We arrived to a clean room with an electric piano, plenty of towels, pillows and sheets, some fresh shower products, and a handful of books and maps of the city. Benjamin was very pleasant to talk to and available to answer questions about the room and Vienna.
The building is on a quiet street with plenty of space to park. Schönbrunn is only a couple minutes' walk away, and the rest of the city is easily accessible via the nearby metro station.
The window looks out to a small garden that offers some privacy and doesn't seem to be used much. We spent a very pleasant evening there watching the stars.
The fridge in the kitchen is small and didn't have much space left when we arrived. This wasn't a problem, since we usually ate out and didn't need to store food there. There were plenty of dishes and cutlery available, and the dishwasher and washing machine worked fine (cleaning supplies were available). The bathroom had a few very minor issues, and there was no hair drier. But overall, none of these issues impacted our stay.
