The flat was true to it's description in that it was very unique, filled with interesting art and conveniently located. Just up the steps near the apt is Sacre Coeur and all the loveliness of Montmartre. Didn't meet Franck since he was traveling but accessing the key wasn't an issue. The sleeping/eating/tub area is below a step ladder which proved a bit difficult to navigate after copious glasses of wine but all and all didn't take away too much from the experience. I wouldn't recommend coming with a large suitcase because it was impossible to get it down the ladder, though the narrow steps seemed very secure. We ended up leaving most of our belongings on the top/ground floor and bringing them down the ladder as needed. Unfortunately we had a bit of a hiccup in that the previous tenants weren't out of the flat when we arrived in the afternoon so we had to wait in a nearby cafe until they left. That combined with the early 10AM checkout the following day was a bit rough but Franck had contacted me a few days ahead of time to alert me to the early check out so it wasn't a complete surprise. All and all an interesting place if you're open to a bit of adventure out of the ordinary.
