Danielle's place was perfect for our needs. It is so central and we found we could walk to most places like the Louvre, Champs Elysees, the Seine and much more. It is a cute little bed sit with very adequate kitchen and bathroom facilities for 2 persons. The bed was very comfortable and yes - at times the street was noisy at night but it is Paris and completely understandable and unavoidable. I took ear plugs and they worked wonders! It is in a great spot surrounded by restaurants within a few minutes walk so we didn't need to travel far for dinner. The front entrance is a bit shabby looking and at first I was concerned, but for no reason. Security was great. You pass through 2 secure entrances before you enter the apartment. There is no lift and you do need to lug suitcases up one floor which does need to be considered if you are older or less fit.
We didn't get to meet Danielle but the cleaning lady was there to greet us and show us the facilities.
It is a very comfortable little apartment right in the hub of everything that makes Paris an excitingly vibrant destination. I would have no hesitation recommending this place for a couple to stay at.
