Identification: Unknown Flowering Vine

Please assist me with identifying this flowering vine(?) It grows in my sisters kitchen area and the flowers smell wonderful when in full bloom.

 

It is a hoya and, yes the smell is beautiful. It is also quite easily to grow from cuttings so if your sister is willing to share.......

Hoya can be propagated even with a single node cutting
