All the other reviews on Airbnb are very much accurate in describing Michael and the flat. The apartment is very well located near Moulin Rouge with lots of access to bars and restaurants and Blanche Metro. The fact that it's tucked away inside a courtyard means you're not disturbed by the area around. With lots of timeless art you really feel the Parisian vibes of the property which is quite charming. Toilet a little on the small side but who cares, Michael's hosting and the apartment itself at the value makes up for it greatly.
As for Michael himself, he was a perfect host. Waited for us even though we arrived late, showed everything inside, gave us recommendations and responded quickly to our messages. Additionally, we asked for a late checkout and he happily accommodated. As such, I thoroughly recommend this Airbnb property to others!
