The airbnb places we've stayed in have been a bit hit and miss, Carolines place was definitely a hit for us. Very clean, quiet, well stocked and had everything we needed. It was also very spacious for the price we paid (I've paid more for smaller places for sure). It's also close to public transport (the RER goes right along the Seine to most of the spots you want to go). It also has a good view, though you can't quite see the Eiffel Tower from the apartment you'd have to step out the front door. Caroline was very quick to reply to any questions over airbnb email, which was perfect. A+++ would stay again.
