I'd say that I'm so lucky to have the chance to stay at Pauline's place during my time in Paris. It's near Châtelet station, right in the middle of the city, with lots of métro and RER lines going through. Even when you just want to walk around, it's a very nice neighborhood. You can go shopping, dining, visiting all kinds of stuff, or just spending time in the nearby parks. The apartment itself is small but clean and well-organized. I stay for almost a whole month and basically it has everything I need - it's like I'm actually living there. Pauline is very nice and warm. I didn't meet her, but she answered to all of my questions very quickly and thoroughly through the messages. I highly recommend the place. If I ever come back to Paris again, it would still be my top choice.
