They have not posted on the forums since. As they'd provided on that thread, here is the Floralia's website in English:

If you have questions regarding the deposit/cancellation period, use the contact info provided to communicate with them. Thing is, cancellation rules may have changed since jconsol stayed with them so best to get the current situation from the horse's mouth.
i will mention being cautious about what their apartments for 4 people will accommodate, as far as beds? Read carefully the descriptions for sleeping arrangements with double beds, twin beds and sofa beds. You will want to make sure both couples have actual bedrooms versus one couple sleeping on a pullout in the living area.
