Madeleine McCann : Was the window an access or exit point? ?

The window where the supposed abductor got through is the one on the left (beige shutters)

I've just finished watching the above documentary on her supposed abduction.

What I'm struggling to comprehend is, if the window was an access point, how on Earth could someone manage to open it from street level and then climb up?

I lived in Portugal for 2 years (in Lisbon, mainly). The shutters are all the same. Granted, they aren't the best, but it's virtually impossible to open them from the outside on your own and without the help of a tool. If the window was an access AND exit point, is it feasible for someone to be able to open the shutters, open the windows, climb inside, pick up the child and then leave through the same windows?

The front door of the flat was open (as stated in the documentary). The intruder may have entered through this door. It's almost certain that he opened the window and the shutters - as the McCanns have always said the window and the shutters were shut the night their daughter was taken.

There are still so many questions that have remained unanswered.
