How can anyone rent an apartment in Wroclaw for just 1-3 months?
Sometimes you can find an apartment that rents month to month - lots of housing in wroclaw. I reccommend you check out the classifieds of some local newspapers.
If you can't find one like this (ie: if you dont speak polish), then sign a lease for 6 months - 1 year and take off after 3 months without telling anyone. They won't come chasing after you because it is too much of a hassle.
lol i always do the latter:)
