What you see is what you get.
The location is realy grate, near everything. But, take in consideration that the street of the apartment is in an alley. So is not so easy to arrive at the first try, be sure to have the specific indications.
One thing we did't notice on the pictures is that the apartment doesn't have any windows, at all.
So, in our stay, there was a moist odor because of the lack of ventilation.
The cleaninnes of the apartment was ok.
But, as soon as we left some food over the table, there were ants all over the food in a period of an hour that we left the aparment. So, be aware of this if you stay here.
That's all, as i mentioned before, what you see is wat you get. I think is a good location if you are in a low budget vacation and don't need any luxuries.
I hope this experience helps you to make your choise in Paris!
