I fully recommend this apartment. Jean is nice and reply message quickly. He also send us one bottle of wine for free. More than that, There are two train stations in 5 minutes walk. These two stations can go to every famous sight spots include tower and Versailles Palace. Hence, it is so convenient that you do not need to take taxi. Finally, the sofa bed is the best one which I have sleep.
To conclude, nice apartment with safety and good price.
