The Radisson is in a very prime location. The Park Inn sits near the Grundwalski Bridge on the other side of the river. I've only stayed at the Park Inn. It's OK. Nothing spectacular. But it sits adjacent to a lot of tram and bus lines that take you to various parts of the city, including the city center. However, there is a major building complex being constructed next to it (which I'm not sure is completed yet). So noise may be an issue.
