We had a very nice long weekend in Paris staying over at Henri's apartment. It's close to the Jardin des plantes and the Grand Mosque, and with a cute walk past the Seine or through Rue Mouffetard you're in the centre. The apartment is small but you don't notice it that much, with a cozy well-designed interior. Sharing the bathroom and kitchen with them was no problem at all for us as everything was very clean. They gave us cultural recommendations in the city and were there if we needed them for anything. Would go again!
