The station itself is clean, but not the street level. You can enter from both sides of the street. There are vending machines on the wall opposite the entrances, there's one for the electronic pay card, and the other is per ride I believe. I got a card, but I thought it was supposed to have a value on it already, and if it did, the turnstile basically depleted the 20 peso value, so I had to add more and I used the other side of the station.
The trains are pretty frequent, not the most clean but will do. The system map is not too complicated since there's only 2 lines. In a way, this metro system is not too much of value for a tourist (although it is cheap per ride), since it doesn't go to many places a standard tourist would go to, unless you are staying at a hotel somewhere along the line. It is helpful to go to Parque Fundidora, however, you still have to navigate a few streets through dirtiness. read more
