Above all, the apartment is just like the same as it's described. It's very clean and closes to the most active street in Paris! The area has been my favorite place in Paris! There are a lot of restaurants, cafes, markets, bakeries, etc. near it.(They're only a few steps away from the apartement!)
The apartment itself is on the 5th floor, but I got used to it.
Blaise was very quick to answer even though he was in the middle of his own trip and he's very flexible about my offer.
Thanks to this apartment, I and my sister had a great time in Paris!
