This is a beautifully designed spot in a fabulous location! Especially if you want to be near Left Bank shopping. As others have noted, the stairs are no joke! Be prepared for some glute-toning, they're steep and twisty and there's a thousand of them. There's no air conditioning and it gets great light (we stayed there in July), but this means it gets too hot and stuffy in the afternoons. The couch folds out but isn't set up for a second sleeper- maybe extra bedding is available if you arrange it beforehand? As others have noted, the key pick-up/drop-off place is actually really far away and terribly inconvenient. Beautiful little view of the back of St. Suplice and Tour Montparnasse, lovely kitchen, surprisingly quiet and tranquil given the cheerful wild bar scene downstairs, very clean, very pretty, great bathroom.
