Best area for flat rent between Kothrud and Koregaon Park

My friend and I are looking to rent a 2BHK together.

My office is in Kothrud and my friend's office is in Koregaon Park.

Both of us have in office jobs, 5 days a week.

So want to take the flat somewhere in middle, so the travel time is optimum for both of us.

Which areas should we look for flat in?
