Couple with two kids and the space worked very well for us. Excellent location in the northern Marais.
Great place to stay on a cute quiet street and a metro/supermarket are a short dander away. No problem getting the key and host was very efficient to deal with.
It is easily accessible from the street, large windows that let lots of light in and yet provide good privacy. They also have automatic shutters that come down for safety at night. It is very spacious and both the pull down bed (kids) and our bed were very comfortable and a proper size. It also has two Large Tv's with all the apps to keeps kids occupied at night.
Very nice to return to in the evening and not have to negotiate stairs like other places we've stayed in Paris
A few small niggles like the mouldy towels that were left for us and a few thing that need repaired (bathroom lights for example) in the apartment but despite these we would definitely stay here again.
