 I found black hair on toilet seat and shower siphon drain seems to be little bit clogged Overall those are the normal things that can happen 
 Location of the hotel is great it takes 15 20 min walking to the Centre Hotel also have garage across the street but decently priced I didn t use sauna because of the nature of my visit to Vienna but next time if I visit Vienna I d like to stay in the same hotel Lady receptionist Carina was very kind
