Oly & Mat were very warm hosts. It's a shared apartment but they make you feel like you have the entire place to yourself, the living room is also directly connected to the room. The room is exactly what it looks like and the apartment has a fantastic location. It is in very close (mainly walk-able) proximity to Notre dame, Louvre, Pompidou etc an everything else is well connected by the metro. The locality is also one of the most alive parts of Paris with lots of restaurants and bars (tends to get noisy on weekends at night). One small hurdle is that you have to climb up to the 3rd floor. Overall it was a great experience and the hospitality of Oly & Mat is worth a mention again
