Multilingual Booking plugin

Hello ?? ,

I have an apartment rental website and I am looking for a booking plugin.
I have allready tried some of them and chose booking calendar ( by wpdevelop ) but I switched from using multisite for diferent languages to using polylang to simply translate pages and posts and now I can’t get booking calendar transate itself when i switch between languages .

Is there any way to make booking calendar multilingual without paying for the premium version ( can a premium version be multilingual? ) ? And if no can you please suggest other good booking multilingual ( preferably free ) plugins .

Thanks !
