If you wish to take a bus to go around the city, you must first locate the official bus stops. Some buses take between 10 to 15 minutes to arrive to the bus stops, some others can take up to 30 minutes, depending on their route (places they go nearby, which are usually mentioned in the front of the buses but you can also ask the bus driver)
You should also know the fee and how long will it take to drive you to your destination and most importantly, you must consider that the ‘busy hours’ in which traffic gets really heavy are in the mornings from 7:30 am to 9 am, on the afternoons from 1:00 pm to three and on Fridays it can last until 4:00 pm or even 6:00 pm.
Another option is to grab the sprinters, which go around the city more frequently than buses but their destinations are quite more limited. You can also grab a cab, however, it is always recommendable to ask how much will they charge you before you get into the cab. Uber is another option.
In our school we have the option to facilitate the service of reliable drivers who can drive you around the city or even outside the city, in a reliable and safe way.
