It was amazing knowing that I was staying in a building that was around in the 1700s. The building is beautifully maintained. However, I think that it is important for those travelling in groups to note that the space is very intimate, one cannot really close the doors of the bathroom and WC.
I would definitely book the apartment again when I spend more time in Paris (I only stayed one night on a long layover). The apartment is on such a beautiful street with many cafes and stores.
