There is a dialogue:
"Which hotel are you staying?"
"It's the same hotel I stayed at last time I was here."
I'd like to ask about the second sentence. If I want to make it short, which sentence is correct from the following?
- (1) It's the same hotel I stayed at last time.
- (2) It's the same hotel I last stayed at.
- (3) It's the same hotel I stayed at for the last time.
Or do I always have to say the full sentence like the first example even in the daily conversation?
