Vu was very easy to get in touch with and very hospitable. They even had a bottle of wine and a large bottle of water waiting for us upon check in, which was nice. The neighborhood is very trendy, lots of shopping and close to main attractions, but it is expensive. Our first stay in Paris was in the 9th arr, which was a little more mellow and more bang for your buck while still being pretty close to everything.
It must be noted that the apartment is tiny. I would describe it as an upscale efficiency. My wife and I were cramped with not much space for our luggage. I would recommend this unit for a single traveler or two with very little luggage.
