I stayed 4 nights at Anne-Sophie's place. The check-in/check-out was extremely smooth and Anne-Sophie is a very lovely person. The communication was very easy and I was given all sorts of tips to make my stay in Paris as enjoyable as possible. The flat is small but clean and well decorated. More importantly, I always felt safe and was able to reach any destination within Paris quite quickly, as the flat is near 2 Metro lines, bus lines and major train stations (Gare du Nord and Gare de l'Est). The flat is also conveniently located near restaurants, supermarkets and boulangeries. I would recommend Anne-Sophie's flat, particularly to those wanting to explore the romantic and bohemian Montmartre area but wanting to stay away from the tourist crowds and noise. Anne-Sophie stayed in touch throughout my entire stay, always wanting to be helpful and making sure I was having a good time. I thoroughly recommend this place.
