Benoit's place is just perfect. I stayed in this house for almost 2 weeks and there was no problem at all(Only the first time when you arrive the house, it's a bit hard to bring your luggage to the house cause there is no lift, but it's just a small problem). The house is same with pictures on website, Very well-equipped kitchen(with many spices) & You can use laundry machine for free & also can use vacuum cleaner. A bed is soft & sofa is comfortable as well. The place is just very cosy all around.
It is in walkable distance from 'montmartre', so I took a walk many times after dinner & enjoyed the beautiful night view. Transportation is convenient, there are 2 metro stations (line 4 'simplon' & line 12 'jules-joffin) in 2 minites walk from the house, thereby you can get to the city center and many other popular spots easily. There are delicious restaurants around the house & some more on the way to sacre coere. Monoprix and franprix are around as well.
I couldn't meet Benoit because he was on his travel, but before his leaving he told everything & every time I sent a question to him he kindly replied, so there was no problem. And when we get there, his dear friend Jelena welcomed us!
After all, the house is just very cosy and valuable. I recommend this place!
