There were 3 (girls) of us staying at Sonia's apartment and we can honestly say it was the perfect place to explore Paris from. It's in easy reach of Gare du Nord and Gare du l'Est and other metro stations, but simply walking through Paris was the best way we found to experience it and Sonia's apartment was in a great location for this. The apartment itself is beautiful and very chic, with everything we needed for a comfortable stay. The sofa bed was not actually a sofa, but 2 mattresses on top of each other, making for a comfortable sleep. Sonia had helpfully left suggestions of where was good to eat, drink and visit in the local area, we took her advice and everywhere she suggested was lovely. It was great to get a taste of Paris from a local's point of view. The stairs to the apartment were hard work and not for the fainthearted (or very large suitcases), but definitely worth it for the amazing view and gorgeous apartment. We had a brilliant time and would definitely recommend Sonia's place to anyone who wants a real Parisian experience. Thanks Sonia for being such a great host.
