the buses are fine if you want to go with the natives. I use it all the time.
Regarding the taxi I dont use them often most times it takes you twice as long . Dropping off to their uncles shops. As for driving They drive like raving lunitics. Also rush hours fumes horindous and in the summer forget it.
By the time you get back to your room your stink of fumes and you are coughing . Not healthy
