Elv and Yan are the perfect hosts. When I arrived, they were quick to help me with my bags, give me towels and supply me with lots of bathroom goodies. They evened supplied me with a power converter which was a very kind thought. Although we didn't spend much time together, they were quick to offer me coffee, give me directions and help me around Paris. The night before I left we actually got to hang out - both of them are very interesting, well traveled people.
The flat is located right off of a Metro stop and is easily accessible from any Metro line. The immediate area has some great local shops, and the Bastille area is full of cafes and bars if you want to eat or hang out at night. All in all this was a great experience thanks to some excellent hosts. Thanks Elv and Yan!
