I just completed a 2 night stay. It was a great stay overall. I'm platinum and was upgraded to a nice suite (room 101) near the club lounge. The room had a nice big sitting area with tv and a bed off to the side. There was no door though between the sitting area and bed.
The club lounge was nice and had 2 hot dishes at night (shrimp, meat, etc.).
In the morning I had breakfast in the restaurant and the buffet was a great spread. They also have an omelet bar. This was included as my spg amenity.
The location is nice since it's near the castle. It's not totally close but not too bad of a walk.
I walked from the train station and it wasn't too bad since I didn't have a lot of bags. If I had some big luggage I would probably take a taxi/uber. It is pretty cheap in Poland.
I did not have a squeaky dragon in my bathroom. I looked for it...but it wasn't there. I didn't feel like asking...
