Predictably, your dollars will generally go further in Eastern European cities than they would on the western side of the continent. But out of all the urban centers in Eastern Europe, one city stands out as a haven for travelers seeking luxurious accommodations at bargain-basement prices. According to the Hotel Price Index from Hotels.com, Poland's capital offers the most luxurious hotels for the lowest prices in the world. A five-star property in Warsaw cost, on average, $130 per night in 2011.
In addition, Warsaw ranks as one of the top world cities offering the best overall value for hotels costing an average of $100 per night. For example, weekend stays cost as little as €65 per night at Polonia Palace Hotel, an opulent early 20th-century property that was the only hotel in Warsaw to survive World War II completely undamaged.
