Just had a great week staying at Valerie's flat in Paris. She was incredibly easy to get a hold of and was very helpful, she even called a car to the airport for us.
The location was great with Notre Dame, the Louvre, and the Left Bank just a short walk away. There's also a metro stop right on the corner that has just about every line you'd need to get to around the city, plus a supermarket on the block to stock up the apartment.
Overall a great place to stay if you want to see all of Paris.
