This apartment was small but comfortable, and well situated in regards to access to everyday needs (pharmacy and grocery store were just about 2 blocks away), public transportation (about 10 mins walk from Metro stop Chateau Rouge), and the Sacre Coeur (it took us more like 10 minutes to walk there). The indoor décor is eclectic and delightful--many books in multiple languages if you are interested in reading.
The pictures of the interior of the apartment were accurate (though it does look different in gray, drizzly January when the sun isn't streaming through the windows :) ).
Towels and bedding were clean, the heating worked well. There was some extra bedding as well if needed. One challenge was lugging our suitcases up the staircase, but that is relatively minor.
David was very prompt in responding to questions I sent him prior to our arrival. He provided us with precise details. He was unable to be present for our arrival, but provided us with the number of the housekeeper in case we had any needs or concerns. Upon our arrival, we had difficulty locating the keys, but this was soon resolved and we were able to reach the housekeeper (who was helpful and kind) by telephone for assistance.
We did find dust bunnies around the mattress underneath the bed that is used to sleep the 4th person, and some more dust around the edges of the living space, but otherwise the cleanliness of the apartment was acceptable.
Note: there is no microwave in the kitchen, but there is a stovetop and traditional oven.
