I see apartment listings saying they have "ELF's"? - 3d apartment extreme download

I have many lists of apartments, who said in the description of additional features which have seen, they were "ELF" ...

For example,

"... Washer, dryer, dishwasher, ELF, curtains ..."

Can someone tell me what do "ELF"?

Heres a link to two of the ads I have not seen yet ...
