We've used the appartment for a pre-christmas weekend for our family (6P) in Paris. Everything was great but above that explicitly worth mentioning was good communication by detailed information provided before check-in, even with a video how to access the appartment. Also throughout our stay our host stayed in close touch.
The location is very central, however in a quiet side street. A boulangerie, supermarkets and bistros are just around the corner.
The beds are really comfortable and the appartment features everything of daily need including shampoo in the showers (good smell!), a Nespresso coffee machine and a free luggage storage. We'd come back next time!
