We spent 7 nights at Carole's place. It is near the metro and very convenient. The room is spacious with space enough for us to have 2 big luggage open. However, the sofa bed can be quite uncomfortable as it is folded in the middle. The toilet is really small and does not have much space to move about but has a really hot heater to keep you warm during winter. Overall, we still enjoyed our stay in Paris.
