Stayed here 2 nights in May, booked the base courtyard facing King bedroom, was upgraded to deluxe/superior room with great view of the river. 50 PLN bar credit got me 2 beers. Diamonds have a separate section in restaurant at breakfast and can also order off a menu or have full buffet. I recommend the pizza at Punto Bianco located in the square next to the hotel. Short walk to WW2 museum.
