Generally it is a good hotel, clean and great design. Unfortunately the staff is overwhelmed on many levels and simple processes are lacking, which does not match a 5* hotel any more. Some examples: after being seated at breakfast and left my belongings and bag at the table in order to get food from the buffet, I came back exactly 3 minutes later to find my bag moved to another place and completely unknown people sitting at my table. This was quite a worrying experience and actually makes the seating service unnecessary.
There is long waiting time for the live cooking (over 15 minutes) and no process to assure the order of purchase (apparently women had to wait for their food even longer, even though the male customer ordered their food after the female customer). I found this a very one-sided, not to say sexist, approach.
Glasses and some dishes were lacking over one hour before closing time and no one refilled.
All in all I will probably not recommend the hotel to my colleagues any more and will get another hotel the next time I visit, service/price ratio was better 2-3 years ago and one had the feeling it was a special place and experience. Unfortunately this is not the case any more.
