This apartment had personal touches, souvenirs, and art that made it feel like being guests of a friend. The hosts were very responsive by email when we had questions. The neighborhood is one of the best in Paris. We didn't do any cooking, since within a half mile radius of the flat is some of the best eating in the city, and there is a wonderful open air market at Place Monge a few days a week from which we organized some wonderful meals back at the flat. The four flights of stairs weren't really an issue--we ranged in age from 29 to 74. The train and Metro are both an easy walk, and the beautiful Luxembourg Gardens are also near. And the Seine is not that far either to walk to. Over the course of the Olympics, 5 of us stayed the entire time (we were grateful for a washer and dryer in the flat), and 8 people came and went, with a maximum of 9 at one time, using all 5 bedrooms. We did not use the loft or attic beds. It worked fine for us with the bathrooms and watching the Olympics on TV. Some of us even used the balcony a few times for breakfast. I'd stay there again with a group of friends. We had a great time--the coziness of the flat helped create a warm atmosphere.
