does an apartment little far from centre available for cheap?
Nor really. There are costs for renting a cheaper apartment that may exceed the money you save. For example, the apartment may have bad windows, which will increase you heating bill. Or it might have a very small and inconvenient kitchen, which means you might eat away from home more. Or it might night be well connected to your place of work, which means that you will have a long commute (particularly nasty in winter). Or it might not have a good selection of shops in the immediate area, which means you might have to spend a lot of time doing your shopping, or spend money on taxis. Or have to get a car. Or you might have bad neighbors. Or any of many possible reasons.
Generally, if an apartment is "cheap". there is usually a good reason for that. If you want to save on housing, then there are two possibilities. The first is downgrading to a two-room (one-bedroom) apartment. The second is to live in a very well connected place far outside of the city. Skierniewice, for example, has excellent and frequent high-speed rail connections to the center of Warsaw, and housing costs are much, much lower. Granted, it is a boring provincial town. But it's a good place if you want to live a quiet life.
Also, when looking for an apartment, it is absolutely vital that you enlist the help of an OLDER, experienced native Polish coworker or colleague. They know what to look for, and they know about transportation connections in the city. They can also negotiate with the landlord. Having the help of an OLDER, experienced native Pole will save you heaps of time and money.
