Identification: Flowering vine??

Can anyone tell me what this plant is?? It was given to me about six months ago by a neighbor who passed away. I had no idea it was a flowering plant until two days ago when it looked like this.....
Please tell me what it is!! It's driving me nuts!

 

Looks like Aeschynanthus or Columnea. They are hard to tell apart.

 

Here is the discussion about how to tell one from another:

Aeschynanthus speciosus.

 

Beautiful
