My wife and I had such an easy stay at Roxanne's flat in Paris. We stayed for 8 nights and although the flat is small, it is more than enough for a week or so, especially considering you'll be spending most of your time touring around the city! And when you do want to travel around, getting there is very easy. The flat is a 1 minute walk to the Pont Cardinet train/bus stop which takes you either into central Paris (3 minutes) where you can connect to anywhere, or on a single train to Versailles, La Defense, or anywhere in the West. It's also a single bus ride to the Arc De Triomphe and Champs Elysees in the West, and also Montmartre, Moulin Rouge, Sacre Coeur in the North. There are several excellent restaurants in the local area (Roxanne has kindly written notes on them).
Dealing with Roxanne was effortless. She was so quick to respond to messages and offer advice on the local area.
