I stayed four nights at this hotel last November. Was a good hotel, rooms were nice and big by European standards. No free upgrade with diamond status available at that time. Breakfast buffet was good but not 20 euro good. I didn't try the dinner buffet. Did not try the pool or other amenities. Also it's kind of crappy that they provide a free shuttle from the airport to the hotel, but you gotta pay like 5 euro to go take the shuttle from the hotel to the airport. Since I was there multiple days they sold a 3 day shuttle pass for 10 euro, I just went with that.
