Frank's place is very centrally located in the marsais which is a great location. Frank wasn't available during the week of our stay so we instead were greeted by his mother.
while most aspects of the airbnb were fine, the bed placement was poor and required significant strength to climb up the rickety ladder into the lofted bed. the comfort of the bed was extremely poor and consequently I cannot in good faith recommend the place to anyone. the bed and pillows were extremely lumpy, full of wires and uncomfortable. after several days at Frank's place I ended up booking a hotel for a night because i was so miserable and sleep deprived. nobody should have to suffer like that while on vacation and it seriously impacted my overall stay in paris. this is just the kind of situation you don't want to be in when you're travelling in a foreign place.
if you are on a tight budget, can handle climbing up the steep rickety ladder and sleeping in an extremely bed, I would absolutely recommend the place because otherwise everything else was fine
