Gilles flat is a great set up and he is a great host. It is spacious and contemporary. The master suite offers nice privacy and the outdoor deck is an urban gem for breakfast, drinks, etc.
The appliances and music system are also great benefits. From a location perspective, you arer minutes from two major subway stops, the Arc de Triomphe and the Champs-Elysees.
Would strongly recommend this for both business and personal travel.
