Serge is a wonderful host! He replies immediately and he even treated us coffee at his restaurant which is also near the apartment. He carefully explained how the appliances work. The apartment is close to the bus and train station as well as walking distance to Sacre Cour. It is exactly as shown in the pictures, very modern and stylish. The beds were comfortable and the space is big enough for four people. When we come back to Paris, we'll definitely stay again at his apartment! Thanks, Serge!
