Very nice and updated apartment in a central location - close to the Eiffel Tower and steps away from the La Motte-Picquet Grenelle train stop. The building felt very safe and we loved the small outdoor sitting area. Communication and check-in were very easy as well.
The only con is that the apartment is very small. I thought I knew what to expect from the photos but it was hard to walk around with the bed down. Also had to sit on the toilet at an angle because the bathroom was so little. Wasn't a big deal for us since we were out all day, but just a warning!
