It's a wonderful little studio apartment with a nice view of the Eiffel Tower. The studio is small, with a nice little kitchen, and a fold out couch bed. It's clean and well kept, and has a nice tile bathroom and shower. It's perfect for one person or a couple for short stays. The apartment/studio is in a building with good security doors and locks and seemed secure.
It's situated at the Sevres-Babylon metro station on line 12, or the Vaneau metro stop on line 10, and it's about a five minute walk from the metro station. There are a few grocery stores nearby on the walk to and from the metro, and lots of restaurants and brasseries. It's a 20 minute walk to the Musée d'Orsay and Orangerie, and a short metro ride to any place you want to visit. We walked to both the Louvre and the Eiffel Tower.
