I grew it for a while. I grew it as an epiphyte, the way they grow in nature, in my greenhouse. It did very well. I had it in the crotch of an Erythina crista-galeii tree, but the Erythina died and eventually had to be removed when the trunk started to fall apart. I put the Medinilla in a container as a temporary measure until I could figure out another epiphytic situation for it, but it did not like that and it went into decline and died. My greenhouse is kept at a minimum of 55 degrees in winter, has extremely high humidity year round and gets to about 90 in summer. The conditions for it in a house would be challenging to meet.
