The appartment is nice and cosy and perfect for a stay in the city. It is quite close to Montmartre, but still the quarter is not too crowded and overrun with tourists. That way you have a little peace at the appartment but can get to all the hotspots quickly.
Mathilde is a friendly host and communication with her was fast and easy. The hole stay was very enjoyable and everything was as expected. I can recommend this appartment without hesitation.
