Yes, it is true that you have to climb 97 steps to get to the apartment but is well worth it. The apartment is old but it has a wonderful fully enclosed balcony and it is in perfect locations. Le Marais is a wonderful part of Paris and Karine is a great host. Her restaurant recommendations were perfect. I couldn't imagine a better place to stay in Paris - you are close to all the major attraction and yet staying in a place that is not full of tourists.
