Laurent is such a great host; she responds to you very very quickly and is very accommodating. We stayed for 5 nights, and they cleaned the place and restocked the towel, etc in the middle of our stay, which I thought was very considerate.
Everything about this place was great except the neighborhood. It's very close to the metro station within several minutes of walking distance, and also within 3-4 blocks, there are lots of restaurants and bars. But, the block where this duplex is located is not very family-friendly. At night, there were many hookers within this block. Very quiet though. I would recommend it to young couples but not to families traveling with children.
