Left bank of the river is more expensive. You can find cheaper apartments on the right bank. Contrary to common belief Praga district is not ugly and dangerous as a whole and has nice locations, esp. Praga Południe. You trade paying less for some longer commuting, as you most probably work at the left bank. If you work remotely it's even more convenient.
