It's a very unusual plant - a creeper with thickish waxy leaves and these plastic-looking flowers. This is three flower heads together - they bloom in a little umbrella-shaped cluster. Each individual flower is probably about 7mm across, so they are quite small.
If it's the same I used to have, we call it (directly translated) Porcelain plant (after the buds) or velvet plant (after the texture of the flowers) in norwegian. I love them, but really don't like the smell of the syrup coming out of the flowers! My former housemates almost threw it out because of the smell. They look really nice though :)
