This is a great apartment! The location is absolutely amazing, within just a block from the river. Once you cross the river you are at the Notre Dame Cathedral. The Louvre and Orsay is an easy walk. An added attraction for us was the tour bus stop for one of the double decker tour bus companies (TooT), within a one minute walk from the apartment. We could hop and hop off the bus at all the major tourist attractions in Paris. When you finish sightseeing for the day you can be dropped off right near the apartment.
There are so many restaurants around the apartment, and you can find food for appetites from all over the globe. It was so easy to have great meals throughout our stay.
We were there in early November and did not need the air conditioner or heat. We could just leave some of the windows open during the day and then close them at night.
Your host, Michel, is very good. He responded to several questions I had before we left for our vacation. He also sends you a very detailed file that has specific information on check in, check out, how to work the washer/dryer, internet name/password, operating other appliances, tv, etc.
If I ever travel to Paris again, I will certainly stay here. I am also recommending this apartment to anyone I know that will be traveling to Paris.
