We happened to be passing through Paris during a busy week with lots of conventions in town, and this was the only place even remotely within our price range that night. Unfortunately, we were also there during one of the many heat waves to hit France this summer. The hotel has no air conditioning and no fans, so it was miserably hot.
As a basic room for a night, it should be fine in cooler weather, and the front desk staff were extremely friendly and helpful. Just beware the canicule!
