Pros (+) Great little hotel very close to Gare Montparnasse. Nice, clean, bright rooms. My room faced a side street, a few floors up. The hotel spans a few buildings in the space, with little winding hallways to travel between them. Rooms are smaller than what we think of in North America, but enough space to be comfy. Breakfast was included in my stay, and was a good continental breakfast, great value!
Cons (-) This hotel is right in Paris on a Main Street. It wasn't noisy when I stayed, but I was expecting its location. Just be aware!
