Lovely little place in the heart of the 1st arrondisement. Think of it as a hotel suite (sleeping area, living room, bathroom), with a fully equipped kitchen. It's one flight up, and it's in a generally busy area, so at night it could be a bit noisy if the windows are open. That said, there is very little traffic in that area before about 06:30, so it wasn't a problem. The bed is very comfortable, and the little dining table is fine for two, maybe three at a pinch. Well located for the metro.
Good value. We would definitely stay there again.
