 Nothing 
 The guesthouse is located in a very central but still quite place just next to Albertina museum and Burggarten Our room has a bit of view of the State Opera It is close to every thing the restaurant on the same street is really good and the main shopping street is about 100 meters away The hotel room itself is very well designed comfortable bed oak floor clean and new bathroom convenient mini bar etc The small backery and restaurant on the ground floor of the hotel is also nice I personally like the Quiche with bacon very much The staff of the hotel is also extremely friendly and helpful The tram station is only 3 mins walking distance away I took the direct tram many lines to the university of Vienna every day Anyway too many nice details I think I will stay in this hotel again if I come to Vienna next time
