The place is really nice, tastefully decorated. It is not a buh apartment but provides space enough go accomodate two persons and feels very very authentic. You have the best view of the Sacre-Coeur from the traditional Parisian balcony (much better than on the photo:).
We were also able to cook for us - there are all the utensils.
The communication with both Natasha and Hugo was perfect, they were always there for us. We had some issues with the TV and Hugo managed to solve everything from the distance in no time.
The two things one should be aware of - the apartment is on the 6th floor and there is no elevator (but hei, there is this view from the balcony) and the location seems to be unsafe, two different uber drivers told me to be very careful. But you have hindreds of small shops and a great supermarket just 4 minutes by foot and Monmartre is like 10-15 minutes by foot.
