The best aspect of Hotel de Paris Montparnasse is the front desk/reception employees. They were all friendly, professional, and answered all my questions. Especially Hassan, who was always happy and smiling, and went out of his way to help. It also has a great location, right across the street from the metro and train station.
The hotel is very clean; the air conditioner worked fine. The only reason I did not give it 5 stars is because there is no mini-fridge, which would have been a great asset. I wanted to bring food back to my room, maybe something to drink, but without a place to store them, I couldn't. A definite minus. There is even a perfect place for one, so there's no excuse.
