We really enjoyed Pierre Marie's place, very stylish and great location. We came during the French Strike, so many metros were stopped, and surprisingly we didn't found it difficult to navigate the city at all! It's located in a local neighborhood, very convenient but not touristy. And the fireplace heater is perfect. The only concern we have is when it's raining, it's very loud inside the room -the roof is a sheet-metal without insulation. It happened to rain 2/5 nights that we were there, and we found a bit difficult to sleep.
