Thank you for a wonderful stay! The apartment is fantastic, very spacious, and a clever use of the space. (We had no problems but others may need to note it may be difficult if one has problems climbing stairs). No such problem for my boys who loved sleeping in the loft bed looking up at the stars.
The location is excellent: a short walk to Le Louvre and a number of Metro stops. I also enjoyed having the Jardin de Luxembourg so close to use for my daily run. The neighbourhood is full of galleries, there is a supermarket close by as well a fruiterers, a fresh fish shop and some lovely delicatessens.
Bruno gave us an excellent and comprehensive introduction despite the late hour and our high-school-only French. He was extremely approachable but also happy to let us come and go.
There is a little cigarette smoke smell from the neighbors, and that may bother people with brittle airways but not us. C'est Paris after all.
Once again thank you so much.
I would recommend Harold's place with no hesitation.
