When comparing prices, the structure matters.

Cheaper than = less expensive
„This hotel is cheaper than the other one.“

As cheap as = the same price, or equally inexpensive
„This hotel is as cheap as the other one.“

💡 Quick tip:
Cheaper than.
As cheap as.

And remember: cheap isn’t always the best word in business. Depending on the context, less expensive or more affordable may sound more appropriate.
