My girlfriend and I enjoyed our 2-night stay at Caroline's place! It's situated above and across from a metro station and church in a lively neighborhood not far from Sacre Coeur. The balcony is a great bonus, and the interior has an authentic Parisian/French feel to it, which is one of the main advantages of airbnb over a generic hotel room in the first place.
Caroline was accommodating with our arrival & departure times and the place was clean and tidy when we arrived.
