Great experience! Apartment accommodations are very nice and comfortable. Having a kitchen with a stove, microwave and a refrigerator and a washing machine/dryer was much nicer than being in a hotel room without those conveniences. The apartment is in a great location. Very close to the metro system and within walking distance to many of the most popular attractions. It was easy to get to and from the airport with the metro being so close. The building is security gated and in a very safe area. Only 2 things that I can think of that were negative. One, the bottom of the shower door has a gap that lets water leak onto the floor outside. It didn't inconvenience us and a towel on the floor takes care of the water but my "fix-it" personality kept wanting to repair it. Secondly, there's a neighbor that walks around a lot at late hours with their shoes on. I wished they would take their shoes off or put down rugs so it wouldn't be so loud on the wood floors.
Minor things really, we had a fantastic time and loved our trip to Paris.
