 Nothing everything was perfect 
 Perfect hotel very very cozy and beautiful with its special character the hotel is situated on the very quiet small street in old city two minutes walk to San Stefan cathedral the staff also is very nice Breakfast is very tasty and includes cold cuts salads scrambles eggs bacon and sausages What I ve liked the most that the combination of a very quiet street in the middle of the old center of the city No doubt that in my next visit to Vienna I will choose to stay here again
