Great communication, quick response to questions. The apartment is nice, basic, clean and in a great location, quiet neighbourhood, easy walk to the Eiffel Tower. Close to metro also which makes it convenient to venture further.
We were a family of 4 staying for 4 nights and although the bathroom is very small, the apartment was spacious enough for our stay.
The only negative is that the upstairs neighbour is extremely inconsiderate, marching across the floor above with heels on late at night and partying with loud music, banging around until 4:30 AM on our first night there... Luckily the following 3 nights were better and we were able to sleep.
Our overall experience was positive and would recommend the apartment if you're looking for a great base to explore this beautiful city.
