I had a great time at Emmanuel's place. It is a prime location and well positioned with all kinds of local transport. Also, many sights are nearby and the atmosphere of the Vth quarter is incomparable with any other district in the city. My favourite spot in Paris by far and I lived like a local which is what I really wanted to do on this trip.
The apartment is as described by Emmanuel. He was very responsive and answered all additional questions that I had. So, you get what you expect and there are no unpleasant surprises.
I recommend this place to others and I will definitely want to go back if I plan to return to Paris.
