If you do, you must stay at the Polski Pod on Pijarska. I'll get you an excellent rate from the manager, who happens to be a pal of mine. Great location, fantastic facilities and rooms, and a breakfast of the highest quality. And if you head out to Auschwitz, stay at the Hotel Olecki. Once again, the manager happens to be mate. And my local connection and guide, Jan, will take you to the outlying areas for a nominal fee.
