This is a lovely room in a trendy, exciting neighborhood (Oberkampf with all its bars and world-class restaurants). NB that it is a room, rather than a full apartment: the bathroom is outside in the hallway, and the host has built a mini-shower in the corner of the room. I wanted a pied-à-terre for the brief time I'd be in town, and this sixth-floor (seventh-floor if you're counting the floors American style) fit the bill accordingly.
Frederic, the host, is a very kind guy who will answer all your questions. I didn't see much of him--I was so busy--but knew I could check in with him if needed. He can communicate easily in French and English, and is full of recommendations. Overall, a good neighborhood, a comfortable room, and a strong value.
