Cheaper than expected. I was staying in the Escalante neighborhood, but before I got there I was prepared for a very expensive 2-weeks, but you can find a meal for $8, haircut for $15, 10-minute Uber ride for $2–$3, gym membership for $35, and a shot of alcohol for $4.
The Spanish is really easy to understand
No military (though there is a small unofficial force that deals with border disputes, hostages, etc.)
Volcanic ash in the air is a year-round issue
The main park (La Sabana) is not well maintained. The man-made pond has really dirty water and all the grass is dead.
