It's free. Reasonably well laid out. Pleasantly presented. Everything's in Spanish so, if you don't "habla" then no real point in going other than to look at old clothes and pictures.

Very informative and a very modern, interactive museum. It's free so it's a good value. It is not very big so it won't take too long, plus is right near downtown so you'll likely be in the area.
