I attended a conference in Parc La Villette and Helene's appartment was perfect for the 3 nights I was there. It was just 5 minutes walking in a very nice neighborhood. The appartment was on the 4th floor (no lift) and was clean and quiet. It has everything you might need except a television and laundry, but I did not need those. There were many restaurants very nearby, and an organic market across the street with nice wines! The metro is right outside the front door! My train was 3 hours late and I did not arrive until 1AM, but Helene was very helpful getting me into the appartment, despite the late hour.
