Wow. What a well constructed, well planned out system is this. The whole system inclusive of the U-Bahn is easy to use. The stations are numerous, well placed, clean, and not encumbered by having to have tickets validated. That's not to say you should try to ride free because if caught the fines are heavy. You can ride with your dog as long as it's muzzled. read more
Great public transportation system with an average of 2-3min wait time during the day! Modern, well maintained and clean, light and spacious, all with elevators (however some of them in remote locations of the stations), larger stations with infotainment screens and some art installations.... Locals really don't need a car to get around in the city! read more
