This is an awesome apartment, perfectly located near the Louvre, Montorgueil, the Samaritaine, and Les Halles.
It's on a quiet side street, easily accessible (only one floor up, but also has an elevator), and has multiple big windows for fresh air.
Sara's also a great host. It was really hot during our stay, and she very kindly provided us with a fan to keep cool. Great communicator, Sara also gave us some very helpful info about local amenities.
I'd happily stay here again in the future. A great find.
