This place was in an amazing location, literally minutes walk to a lot of tourist attractions and surrounded by bars/restaurants. I would definitely recommend this apartment based solely on location and the fact that it is much bigger than the pictures suggest. Rodolphe and his partner were very hospitable and easily contactable throughout.
The only downsides being that we were told we could only check-in at 6pm on the day of arrival - this didn't effect us too much as we arrived in Paris at 4pm, however this would be unfair if you were expecting to enter the apartment at the stated 3pm.
Don't expect to be making any food in the apartment as the cooking facilities are lacking. Again this didn't hamper our enjoyment as we had picked the apartment based on location, but something to think about if you are wanting to make your own meals.
