After a very leisurely lunch

...we burned off the many calories with a walk thru the streets towards the Seine eventually succumbing to the heat and effort so we jumped on the Metro.

Metro was clean and efficient and with windows that opened the carriages were well ventilated and cool, unlike most of the London tube which is stifling and unpleasant if on sets without air-conditioning.

Jumped of at the Ile de Cite station for a walk round the island.
