Marc's apartment in Montmartre was everything we could have hoped for in Paris. The location is wonderful, surrounded by great little restaurants and neighborhood shops. The flat itself was comfortable and perfectly clean, with a very comfy bed and lots of space for us. One evening after we'd been at the Gare de Nord, the international train station to book another leg of our trip, we had an easy walk back. It's also 3 blocks from the Anvers Metro station.
