Simply the best Metro/Subway system I have been on, compared to at least 12 or more cities, such as Washington DC, London, Paris, Rome, Athens, San Fracisco. What to say. The highly automated system worked flawlessly every time I've used it in over 4 years. Cleanliness…
From entry into the stations the staff are very helpful and patient, we used the metro for several trips including a day ticket where we did a lot of travelling. Trains were clean and regular and sometimes busy but always felt safe.
In Dubai I usually drive a car, but was very interesting to explore Dubai Metro. I never seen so clean Metro in other countries.
Clean & affordable, the metro is useful if you're going across longer distances eg from one side of town to the other when it is alot cheaper than the very expensive taxis. Walks to & from the stations can be very long
The Metro is clean and bright, given that it is above ground for most areas. The only issue is the fact that it doesn't cover all the city.
