We stayed at Anne-Christine's apt with my adult daughters and their boyfriends for Christmas. The apt, in a classic Haussmann building has been recently refurbished with wonderful amenities, including a great washer/dryer, large screen TV and access to multiple channels (although our time was mostly spent exploring Paris). The furniture is mostly Ikea but functional. The kitchen was modern with a nice stove/oven and microwave for those who wanted to cook and eat in. There is also a nearby (short walking distnance) mono-prix supermarket.
Our host was prompt to greet us at the apt, provided quick response to questions and and kept clear communication. There were two metros nearby, each easily within walking distance. Republique is a nice area and offers access to most anything in Paris needed and offered easy access to fine bakeries and lots of local restaurants of various cuisines. There were a few slight issues, including Wifi that was unpredictable (usually functional but sometimes slow) and one of the three bedrooms was somewhat small, although the all bathrooms and showers worked well. Overall a great experience and easily recommended.
