Has this "Periodic Tenancy"... ...something to do with the so-called time-sharing?

Swift Translation Oct 31, 2013:

context, please Could you please provide more context? It's not an easy task to translate a phrase not knowing the sentence it comes from, or if it is a headline and what is below.

Besides, if you have problems with ALL the legal terminology, you may be unable to translate the agreement accurately, so I suggest you should hire a professional translator to do it. Don't get me wrong, I'm not advertising my or any of my colleagues' services here, I'm simply pointing out that the prospective tenants may find it difficult to understand the agreement in Polish if you translate it, say, not well enough, and your effort may be simply pointless.
