The apartment is spacious and lovely. It is about a 10-15 minute walk to the Montmartre/Sacre Coeur area (lots of stairs to climb) and a 20 minute walk to the Moulin Rouge area (no stairs). Trains very close at Barbes-Rochechouart are less than a 5 minute walk, and Gare Nord is just a 10 minute walk. We never had any problems, but it has to be said that the area is crowded with many loitering young men just standing around. Just something to be aware of, that's all. Nice surprise is that there is a great Farmer's Market on Wednesdays and Saturdays that you can get just about anything--Fruits, Vegetables, Meat, Fish, Cheese, Chocolate, as well as clothes, and kitchen supplies. Communication with Adriana was great. She was quick to respond to questions. We would definitely stay there again and would recommend her place.
