Guillaume is a very nice person, he has welcomed us and given us many suggestions for our trip in Paris. He was very available. The apartment is very beautiful, clean, it's like staying at your own home! I highly suggest this place for you stay in Paris, there are both subway and bus near the house (no more than 200 m by foot), and in less than 15-20 min you're in the center of Paris. Excellent quality/price ratio. If I'll ever return back in Paris, Guillaume will be my first choice :)
