This property is reasonably easily accessible and incredibly reasonably priced for Paris, but visitors should be prepared that 4 stars in France apparently means there is a lift, beds, and a shower.
The room we had was extremely small, the lift is very old-fashioned and even features markings of a previous hotel (some may find this charming, but I prefer my lifts less rustic...), and the air conditioner leaked all over our room on the first night so we survived the remainder with the window open as apparently no French repairmen work on weekends.
The staff were reasonably friendly and the room, in spite of its smallness, was clean and updated. As noted, it was quite easy getting into Paris and for a fraction of the cost of a central Paris hotel - this is idea for those looking not to spend much without having to stay in hostels.
