big nice apartment, very comfortable for 4 adults, very kind owners
stuck in the middle of town centre in a pedestrian street, little bit noisy on the weekend nights (but it's 4th floor)
you won't need any transport to go to most of the things to visit in Paris (louvre, sainte chapelle, notre dame, orsay...)
We took RER and METRO to go to versailles, eiffel and montmartre
RER station, from CDG airport, stops 200 meters from the apartment
