Katia and Olivier's apartment was a very cozy and wonderful place in staying with my big family. Very close to the tower Eiffel so we could go out to walk every day for a morning walk. Especially, we got to know why Katia became a super hose in Airbnb. She was not only very kind but also have tried to assist our family in all aspects so we could concentrate on our trip. Katia's house is on the fourth floor, but as the concept of stairs in France, it was similar to the 5th floor that we generally think of because it starts with the ground floor(0th floor) in France. As the elevator of this apartment is in progress of the construction for the replacement with a new one so my parents and kids had a hard time climbing the stairs a little bit, but it was not an important factor for us as there were many other amazing advantages what this apartment has. If you are looking for lodging near the Eiffel Tower, I'd like to strongly recommend you to select here.
