Eveything fine. Easy accesbible (be only careful with parking during working days, way how it is organized in Vienna is a nightmare), non-problematic contacts, perfect location - on foot 15 minutes to Schonbrunn, 25 to the city center, silent, clean, big enough however not extremly modern I would say.
If you can accept the price everything inside will meet your expecattions for a shorter or longer stay.
