I didn't actually meet Mat in person, but he was incredibly helpful with getting me keys, making sure I had easy, detailed instructions to get in. The apartment is great, just as described, with a comfy bed. Washer/dryer was key! My only criticism is that it's a LOT of stairs to get up to the apartment, but we could all use the exercise... Amazing location, right by the subway and within walking distance of Champs Elysees, the Louvre, and Notre Dame cathedral.
