Marc was a wonderful host and his flat is a nice cozy place to stay while in Paris. Paris is a big city so be prepared to take the busses or trains. But you can't beat a 15 minute walk from the Louvre!!
Marc's flat is extremely close to the metro and the busses and is beautifully located right down the street from L'Opera. It's in a safe neighbourhood and is in a very quiet area. We were happy staying here and would again!
