This is a great apartment right in the middle of Marais. It's great for a family stay with a bedroom for parents and a bunk bed for kids. There are also a pull-out and a smaller couch in the living room for more people. The place is right next to the Center Pompidou and several subway stations which allows for easy access to the rest of the city. There're plenty of quality restaurants within walking distance (all kinds of cuisines, not just French) as well as pastry shops and a supermarket around the corner. The only downside is that there're a couple of clubs downstairs that produce a lot of noise for people sleeping in the living room but with closed windows most of the noise is blocked.
All in all, we've had a wonderful stay there and the hosts were very helpful, friendly and communicative.
