3-Layer without repositories, with entity framework?

I've decided to ditch repositories, instead I will use them directly in my services. However, I am now not sure where my EF DbContext should sit and where SaveChanges() should be called from. Here is my current design:

• MVC Client
  • View Models
• Core BLL
  • Domain Models
  • Managers
  • Services - Used to talk to third-parties and DAL
• Data DAL
  • Entity Models
  • DbContext

Should services sit in BLL, or should that be in the DAL?

Also any improvements you could suggest on the above are welcome, thank you!
