Just a gold, but got upgraded to a suite at DT Košice. Booked king room, got pre-upgraded to king deluxe at T-72 and then further into a suite around noon on the day of arrival.
I haven't checked in yet, but based on my memory, their suites are fairly small. Still, going all the way from the basic room to the best they have in the hotel, even as a gold member, is pretty nice

The stay is for 2 nights over the weekend.
