We loved our stay in Le Marais. The location was central and there were amazing shops and restaurants nearby. The Hotel de Ville station is also just a short walk from the apartment which made it very easy to navigate Paris.
The restaurant next door, Le Braque, has amazing food and an unforgettable atmosphere. The owner and his friend/employee, Chris, were unbelievably friendly and our dinner and conversations with them were one of the highlights of our trip.
There was a strong odor coming from the bathroom, but the bathroom was clean. I think the odor may be due to the age of the building combined with moisture and lack of ventilation.
The positive points of the place outweighed the bathroom odor issue and I would absolutely stay here again.
