 The parking is a joke The street of the hotel is very small and can only accommodate a small numbers of cars If you arrive at the hotel before people that live on the street return from work you should find a free parking space if not you will have to pay 10 euro day at the hotel parking So hotel parking is not free However if you arrive before 5 PM you will find a free parking space on the street and you can reach the center by bus 
 The rooms are spacious So are the bathrooms Location is quite far from center but very close to a bus station The bus has the Opera house as the last station so it leaves you in the center of Vienna in about 17 minutes
