The apartment has a really good position, it is near "Les Gobelins" metro station and you can easily reach every point of interest in Paris.
The apartment is disposed over two floors; the kitchen, the living room and a small toilet are at ground level floor, at downstairs we have the bedroom and a bathroom (without WC). There are no windows at downstairs and there is a too small window in the kitchen. A big window is available only in the living room but it is on the street level.
Anyway we found the apartment fine for our one week long visit of Paris.
