Cleon managed it in the books easily enough, he just assassinated the council set up by Dany. Of course this would be harder since it isn't a puppet council, but I believe the battle wouldn't extend into the streets, but more a skirmish in the main-building where the Good Masters reside. The moment they die, it's not like the slave soldiers would try and continue fighting...Hypnos said:Sure why not? But don't expect it to be easy, taking Astapor will be a living hell.
Trying to take Astapor by force of arms would be suicide through rebellion! The Unsullied would just shred everybody.
