The flat is as described, small and Parisian in a great area. Pull out couch was very comfortable to sleep on as well.
We had issues with check out, not because of the host or flat, but the concierge service used to pick up the keys harassed us, shouting at us in the street that they had better things to do on a Sunday and that we should just stay in a hotel next time. We borrowed a second set of keys from them for the weekend and they were just not happy to have to come back and pick them up. Rude behavior, please never hire them again!
