Jacques' apartment was great. Quite small, but comfortable and it had everything we needed for our stay. The location is pretty decent, just a short bike or metro ride to the Eiffel Tower and any other main attraction.
Communication with Jacques was easy, he always responded quickly and gave us great directions to find and get into the flat. Our only issue was that construction has started directly outside the window, beginning at 7am on weekdays and was very loud. However, we knew that this was out of Jacques' control and the construction ends fairly early in the day so we didn't have much trouble with it otherwise. We would still happily recommend the apartment to anyone with a short stay in Paris.
