This is a beautiful space in an absolutely perfect location. You can see the Louvre's building and walk to the metro very easily. There are also tons of restaurants nearby and you might never need to leave that street for all of the options.
Other than the pillows being quite thin, the bed was very comfortable for two. There are two massive windows, which are stunning, and the small heater absolutely heats the space if it's cold weather.
The one thing about this place is that it's listed as "Alain's" but we've never heard from or interacted with someone named Alain. This place is run through a company called Home to Home and they are just down the road from the building. It means that this isn't quite the Airbnb experience of someone letting you into their apartment but rather employees doing their job. There's nothing wrong with that, but it just confused me at first since I was always interacting with different people so I thought I'd mention it here.
We also had an unsettling check-in experience where we were waiting with other Airbnb guests for someone to arrive but they arrived late and were unresponsive to messages because it was a different person letting us in than had been messaging us. If you are also punctual this could be a little worrisome but luckily Home to Home is just down the street so if I had known that before I would have been more relaxed.
