I highly, highly recommend to anyone looking for a place in Paris to stay at Benjamin's apartment.
I stayed for 4 months, studying the language for my doctoral studies.
The location is unbeatable-- you have moffentard, the louvre, sorbonne, and notre dame and subway all in walking distance, and, the area is filled with locals (you only see tourists on the holidays). Boulangeries/cafes/restaurants in tourist areas are quite expensive and highly overpriced, however, in the local areas you will have a more local experience and the price is far better.
I will be recommending this apartment to my friends/family.
