This is the grape leaf ivy, a climber with tendrils. Native to the tropical Americas it is known as Cissus alata or Cissus rhombifolia or Rhoicissus rhombifolia. This is probably not the 'Ellen Danica' cultivar as that has oak leaf shaped leaves. As an interior plant this was not one of my favorites. It did well in indirect light but when the leaves die they get dry and crispy and are a mess to remove. It is susceptible to powdery mildew. I found the best treatment was to cut it back hard to just a few stems and move to a different location.
Flowers are insignificant. Bright indirect light and a soilless mix that drains well are good choices. Does not tolerate overwatering and some sites indicate water should be cut back in the winter.
There are numerous species which exhibit a wide variation in leaf shape. Some are succulents, some have leaves like begonias and others are like shrubs.
