So here a the Paris pics..and no matter where you stay ..you'll definitely walk a lot (London is no exception ;) ). If you wanna see the whole city you should better be gentle on your feet...comfortable shoes are definitely a MUST!!! The last pic is showing you the inside of the euro train. We used this type of transport (from London to Paris) because it's quite diffrent and a nice experince. Our whole bus went inside the train and after 40 minutes below the sea you're already in France.
