Am I crazy for not taking a full time job with 37.5% higher pay?

Planning on turning down a job at a company (same position, more or less) that is less desirable than my current one. However, the pay will be 37.5% more.

edit: wanted to point out that I just started this job not too long ago and I'm just starting to get to know everyone and the processes... and the location is downtown vs not downtown...
