Isabelle's flat is located in an ideal spot, in our opinion, for visiting Paris. You are in the heart of St. Germain! The apartment was spotless! As with many, many flats in Paris, you need to be able to climb stairs (3 flights - not a problem for us) and then the 'main' floor is another flight of stairs. The AC was a perk for us, but Westerners need to know that it is not central air. The unit did cool the bedrooms, which are on the entry level, as long as you left the room doors open. The flat was comfortable and lovely -- a great place to put your feet up and then get going again. Isabelle's English-speaking daughter-in-law was also very helpful. We return to Paris regularly and will definitely rent the flat again!
