Language barrier in Chiang Mai — worth learning basics?

Planning my first trip to Chiang Mai and wanted the latest intel.

Specifically interested in:
1. Current price ranges
2. Best areas to base yourself
3. Safety concerns
4. Quality compared to Colombia?

Any recent reports appreciated. Thanks.

Good info. I'd add that early evening is the best time to go.

Hmm, different experience for me. Prices were higher when I went.
