First let me start by saying that Salmane is the most responsive host I have ever come across. He answers all your questions and as long as you tell him what you need, he is very flexible. We got in on Christmas day and because of the holiday, traffic & getting out of the airport we ended up arriving later than expected to the apartment. He was so gracious about the time.
The apartments is roomy and comfortable for two people, three would be pushing it. If you allergies or asthma I would warn you that when you first walk in, it can smell like cigarette. Once we opened the windows and got some fresh air in, it was fine. The street the apartment is on can get noisy if you leave the window open.
The location is perfect, about a 10-15 minute walk to The Louvre. The neighborhood has plenty of restaurant's and was very safe to walk around in the middle of the night.
