This is by far, the best children's museum we've been to. You could spend a whole day here and still not see it all. My husband took my 6 year old and they only got to 1/3 of the museum. I had the 4 year old and we managed to almost do it all in 3 hours. Most of the information is in spanish, but there are some english signs. The museum staff were friendly and some spoke limited english. The museum itself used to be a penetentiary so it was interesting to see how it was transformed. Bit of a dodgy area though so make sure you have transportation.
