I stayed there again for a couple of nights and seems they have listened our feedback!
No more dust on the elevator mirrors though the led spot & mirror setup is really problematic in that sense.
The lounge offering has also enhanced a lot and now seems to be one of the better lounges I've been to (by the food offerings) though the service hours for the evening cocktails and "snacks" are only from 18:00 to 20:00.
Some pictures of the lounge offerings:

This time they didn't have any IT or key card issues although I had to join couple of reservations and I had two rooms for the seconds night etc.
Also the service at the breakfast was faster and more consistent.
I'm happy to see the positive development of this property the and already traveling back there next Monday.
