If you are planning to visit the Schönbrunn Palace and Park then this apartment is perfectly situated in the right place for you as it only takes about 8 minutes to walk there from the apartment. Also you can easily catch a tram locally to reach the nearest underground train to take you into central Vienna where you can visit Stephans Dom (Vienna Cathedral), The Royal Opera House and the famous Hotel Sacher or you can remain fairly local (West Bahnhof Station area) and take a walk along the MariaHilfer Strasse where there are plenty of interesting shops to visit.
The bed offered is extremely comfortable and the apartment is clean and very spacious! You will find a very useful large desk in your room plus free wi-fi.
Raphael (Oliver's twin brother) was very polite and helpful to me and so was Irene who is a very lovely permanent lodger at the same apartment.
I would definitely recommend staying at this apartment especially if you are very interested in visiting the Habsburg family's Summer Residence - The Schönbrunn Palace and its very beautiful Park.
