London locations

Hello, can anyone help with the search of the following locations please? I drove through Kensington Road but could not recognise what I thought I would find.

At the beginning of the film, the nanny crosses the road . Where?

Where is it located the chemist where the pram was stolen in the film?

Where is the house of Simon's parents?

I have a bad feeling a lot has been knocked down since I have seen so many new built.

Thank you for your help.
