We enjoyed the apartment. We used the bike rentals around the corner as our main mode of transportation around Paris and loved getting to know the city better. The apartment is about 200 sqft so two is plenty in the space even though there is a second loft bed (which we used to store our suit cases). A third child would work, but not another couple. Street noise at night was midi gated by closing Windows and turning on the air unit at night (August). We loved drinking coffee with the windows open in the morning as the city woke up.
