Raphaël's place is very centrally located, yet in a cute little street that avoids the excess noise of the big streets (to some extent but hey this is central Paris!). It has 2 rooms and easily accommodates 4 adults (or more if you are willing to settle down for a little less comfort). It has all the amenities that you could look for a pleasant stay.
Raf is a great host and is always available for any assistance.
A definitely good address
