Emon's apartment is brilliantly located, near to Saint Michel and Saint Germain, so there are lots of bars and restaurants around. It is also near the river and lots of sights.
The RER and Metro are around the corner, so it is easy to get to lots of places.
Emon meets you on arrival, and checks in to make sure you are settling in. He is very friendly and helpful.
I would absolutely stay here again
