We spent a couple of days in Paris in this lovely apartment very close to the Montemarthe. It felt very homey and Etna the cat was such a treat. The host was also extremely helpful with advice around Paris. I would recommend this apartment as it is a short walk to the train station that can take you all over the city. For us it was not a problem to climb 6 floors of stairs to the apparent but keep it in mind if mobility is going to be a problem for you.
