Mathilde was a very kind host, replied very fast when we had questions and recommended some restaurants to us. She organized that a friend of her could welcome us because she couldn't make it, which worked perfectly.
The appartment was as expected, very clean, good view from the balcony, a market with fresh vegetables and fruits directly on the place across the street. Metro station was just a few minutes away from the appartment. I would definitly recommend this place.
