Auschwitz to Prague
 

I am having trouble finding any hotels that have been reviewed by previous guests between Auschwitz and Prague (closer to Auschwitz).

Any help would be appreciated.

Many visitors to Auschwitz probably stayed in Krakow, and you'll find lots of information on hotels in that city.

We stayed in Olomouc, Czech Republic at the Hotel Gemo. Unfortunately doesn't meet your request of closer to Auschwitz but Olomouc is a nice sized city with a lovely main square and adequate hotels and restaurants. Not sure how far west you want to travel from Auschwitz but you may want to consider it. We found the Hotel Gemo sort of by accident but it was modern with good sized rooms, great bathrooms, parking and a convenient locaiton. Good luck in your plans.

Auschwitz is near Krakow, not Prague.
You are talking about 2 different countries.
Krakow is not a quick trip to Prague either. 12 hours by train, 10+ by by bus, by carat least 6 hours (hopefully with a driver as road signs and construction makes it difficult for non Czecks and Poles due to road signs..etc.) and round about routes plus expensive by plane.
Plan accordingly.

Try this hotel - right in the town of Oswiecim, which is next to Auschwitz. Seems very reasonable -

Polish name for Auschwitz is Oswiecim... Auschwitz (Oswiecim) is near Krakow (about 30min by car/bus/train) with good connection ...
So best be to find a hotel there - since you will have much greater options not only as far as hotel goes but also restaurants ...
