I had a great time at Mathieu's apartment. It is well-located, with easy access to metro lines 12 & 13 (and 4), convenient bus connections (the bus station to Gare du Nord is 5 meters from the entrance), and the opportunity for wonderful nighttime strolls to Montmartre. Supermarkets are close by. The room is large and bright, with a high ceiling, stylishly decorated, with a large comfortable bed and a sofa. At night, the room was quiet, and dark if one closes the window shutters. The apartment is nice as well, with a good bathroom and kitchen. Mathieu is a great host, and I enjoyed friendly chats in the evening. Strongly recommended!
