Provided you’re happy to climb to the third floor, Junior Suite is perfect on every score. Light pours in through tall windows, the bedroom faces a tiny street (traffic? You can barely hear it), the detailing is tip-top and everything’s folded, fluffed or shining. At 40m2, this flat is not large but it’s cleverly laid out and as homely as can be. Off a tiny hall is the living room – no sofa but comfy chairs at the dining table, and a fridge-and-microwave kitchenette – a small bathroom to the right and a delightful bedroom to the left. Beds (made up as a queen or two twins) are topped with feather pillows and lovely linen, there’s a large TV and books galore – including some fascinating old travel journals – a polished pine floor that has aged gracefully, and some elegant oriental antiques. Welcoming you with bathrobes, kimonos, extra towels, umbrellas, croissants and a bottle of wine is Belgian-born Catherine, generous, well-travelled and living on the fourth floor. She knows all the places to go, from restaurants and delis to Notre Dame and the Jardin des Plantes, two minutes away.
