My husband, daughter, and I just returned from our trip. We stayed at Matias' apartment for 4 nights.
Location - Walking distance to the Champ de Mars/Eiffel Tower. Metro and buses also are close by. Rue Cler also is a few blocks away.
Apartment - Very clean and well laid out. The pull out couch was very difficult to navigate and wasn't the most comfortable but it shouldn't be a deal breaker if you're thinking of renting the place. Others have mentioned the size of the bathroom and I agree the shower is a bit tight but again, not a deal breaker.
Great restaurant near by - Cafe Constant and two amazing bakeries for your morning croissants/baguettes cravings - Les Gourmandise d'Eiffel and Boulangerie Laurent B.
Thanks for a great stay Matias/Luz!
