 Nothing 
 Excellent location great interior decor and very helpful friendly staff But what I liked the most was that breakfast was available until 11am I m not the earliest riser and it slightly annoys me when hotels set their breakfast up between 6am to 9am or something silly like that I was able to get up leisurely not set an alarm and toddle off to breakfast when I wanted to The breakfast was also amazing If I go back to Vienna which I will because it s beautiful and we loved it I will stay at Hotel Capricorno
