Nice apartment with thick white fluffy towels and immaculate white sheets which always feels a bit luxurious. Area not a classic tourist area but plenty of nice little cafes and restaurants around. Jardin de Luxembourg is close and has a large children's playground (you have to pay to go in but it's a few euros and valid all day). WARNING for those travelling with SMALL CHILDREN: the lift in the building is absolutely tiny and the vast majority of strollers would never fit in it. Probably not for wheelchair users either.
There are some strange equipment omissions (champagne, cocktail and beer glasses but no wine or water glasses? In France? And a washing machine but no drying rack) but I imagine that's easy to fix.
