Went there for a weekend with our 2 twins, 1.5 year old.
Hotel had no elevator which caused a problem an inconvenience since we had a twin troller, so every time we went out and back we hade to ask someone from the staff to help us with the twin baby stroller. Sometimes help was not available - which of course is not OK for a 5 star hotel.
Also - at a 5 star hotel you would expect room service always to be available, but when we wanted to order food to our room 19.00 CET on a sunday it was not possible since the staff had gone home. NOT OK for a 5-star hotel.
Location is 5-star. Room is almost 5-star - but no elevator and poor service should really put it down to a 3 och definetely at most a vage 4.
