Perfect location...the room and the house in general are nice but neglected...the room is to low to let a person to stand up properly...the livingroom/kitchen quit messy and not very clean ( I understand that having children is not that easy to keep tidy the house but I think I should know that before).
Bathroom dirty, especially the sink.
I think that if you have guests in the house you have to make sure to leave a helty and comfortable ambient...to be honest, Paris is quite an expensive city to find to sleep but is recommended to spend a bit more and pass a comfortable night.
