The flat is very nice and clean, the location is great: very convenient to the metro, and within walking distance to the Eiffel Tower. I also walked to Notre Dame, which is a nice walk.
Léa is a fantastic host, she went out of her way to help. She speaks perfect English, so communication was not a problem (for me). The only problem that we had was a miscommunication on my arrival day/time due to my delayed flights and trying to communicate 6 times zones away. This I blame on myself, and Léa was very kind about the mistake (I should have been more careful when saying "tomorrow").
I highly recommend, and would stay here again.
