She added that the Metro would be a "big plus for Dubai" and that it would help ease the city's traffic problems.
Other passengers reported difficulties with buying tickets at Financial Centre station.
Altas Shaikh, 29, a financial consultatnt who works in DIFC, said that although he enjoyed his first journey he found purchasing a ticket "confusing".
"It was a little confusing buying a ticket. The staff were pleasant but it was their first day so they were a little confused," said Shaikh, who began his journey at Union station.
Meanwhile, other passengers making their first journey on the Metro had a better experience.
Ronald Williams, a 28-year-old graphic designer from Pakistan, who travelled to work from Deira City Centre to Financial Centre station in Downtown Dubai, was impressed by the service.
"It was a lovely experience. Dubai has done a good job," he said. "I wasn't expecting so many people on the first morning. The trains are spacious and you can use Wifi," he added.
Williams said the Metro would save him "a lot" of money commuting to work everyday now he does not have to take taxis.
The $4.5bn transport system was officially opened on Wednesday by Dubai's ruler, Sheik Mohammed bin Rashid Al Maktoum, but commuters were made to wait until Thursday to use the service, which has opened on schedule but over budget.
Labourers and engineers have been working around the clock to ensure the project opened on time.
However, only ten stations have opened out of 29, which are to be completed by February next year.
While the project has taken four years to build, it has risen in costs by an estimated 75 percent.
This week the Roads and Transport Authority (RTAsaid that costs will overrun to around $7.6bn.
With nearly 75 km of magnetic track, it is the largest automated driverless train system in the world.
The Red Line, which opened on Thursday is 52.1km, and the Green Line, 17.6km in length, is currently under construction and due for completion in a year.
On the Red Line there will be 24 elevated stations, four underground, and one at street level.
Up to 11,000 passengers are expected to use the Metro in peak times every hour, with nearly 75,000 predicted to travel daily on the service.
