I don't know if there is a hotel, but there must be motels owned by Poles there. Even though Jackowo is becoming more and more Mexican neighborhood now.
Can you overlooked Polish Hotel? There are lot of Polish Neighborhoods in Jefferson Park, Niles, Park Ridge, Norridge & Harwood Hts. Some are located in NW Suburban area and south side in Chicago.
I am sure there are hotels or motels around there.
Never heard of Polish Hotel. If you want to be near Polish Embassy in Chicago Downtown. There are plenty of hotels to your tastes.
