 Nothing It s perfect 
 The best hotel one can find Best location comfortable super clean great and helpful stuff they explained recommended places and restaurants and booked tickets for us The breakfast is also super and very pampering In the weekend they put surprise presents for us We stayed in a maisonette room which is perfect for a family 2 floors and the upper floor is for the children Each floor is spacious and comfortable Bathroom is large and has 2 sinks Also this unit has a a small storage room The hotel is located in a street from Stefan platz and it s the best central location yet quiet In the evening there is a very nice ambiance in the atrium lobby bar We will definitely stay there next time we arrive
