My best and final tip for traveling with toddlers in Paris is to rent an apartment for your stay. Often, apartment rentals can be cheaper and more convenient than hotels. There are a number of websites that offer apartment rentals. Check the Paris visitors bureau for apartment rental links. We chose an apartment in the 8th Arr. through Homeaway.com. Homeaway lists rentals for apartments and houses throughout the world. I found it easy to reserve the apartment with the owner. You will need to sign a contract and pay a deposit in advance of your stay. Typically, the balance will be due in Euros upon your arrival. I booked an apartment with rave reviews and the process went smoothly. We were especially happy with the views (see above) that the apartment afforded and the easy access to mass transit. Having an apartment with a kitchen and in-home washing machine and dryer cannot be underestimated when on vacation with children. If you have a smaller child, I recommend selecting an apartment that is either on the ground floor or located in an elevator building; many of the old apartment buildings in Paris do not have elevators. Bon voyage!
