Based on what I could find, house elves from the Harry Potter world enjoy their duties when treated well. I wouldn't mistreat my house elf, so he/she would extra love being my house elf.
  1. have my house elf teach me how to cook/bake
  2. have deep talks while eating that cake we baked together
  3. gossip
  4. travel
  5. clean together
  6. ask for a second opinion on something I think I like
  7. if my house elf wanted to be freed, we'd shop for stylish clothes for them to wear
  8. have a dance party in the kitchen
