The weather during our stay was much hotter than expected, so we felt that air conditioning (at least in the bedrooms) would have been nice, but at least appreciated that there was a fan in each bedroom. The bathroom was much smaller than expected. It was difficult to move around in - and again, in extreme heat, you would come out of the shower and by the time you manoeuvred yourself to get dry in the bathroom, you were all sweaty again. :) That's nothing against the place though - again, that's unfortunate weather. So a head's up if you're planning on travelling during very hot weather - you may wish to look or a place with air conditioning and/or fan system in bathroom.
That being said, the place is exactly as advertised - beautiful, charming, stylish and in a great location. If you do the Best Kept Secrets e-bike tour (highly recommend), you're only a 10-12 minute walk from the meting place. You're also a 15 minute walk from the Louvre. There's a great restaurant jut outside the apartment where we went for breakfast twice - The Frog & Underground - must check out. Patricia was also lovely and easy to communicate and deal with. Note that the apartment is above a place called Cafe Oscar - don't worry, you won't hear thudding and loud music all night. Only on Fridays and weekends I think, they have a comedy club there and they play loud music to introduce the next comic (very quick) and they only do this a few times during the night. We thought we were in for a night of loud music and no sleep, but it was actually quite fine. I would definitely highly recommend a stay here.
