We had a wonderful stay at Julien's apartment. The place could not have been cleaner or more comfortable. Wonderful working hot water heater, new bath fixtures with shower and tub, and very nice kitchen appliances. The beds and bedding were high quality. We did not hear any noise from neighbors. We did hear city noise when the windows were open, but you will have that anywhere in Paris, and it was never so much that we wished we stayed elsewhere. In fact, if I were booking another trip it would be the first place I tried to get. I was there with my 84 year old dad and my 19 year old daughter... they found only positives about the place and especially the location. 5 minute walk to the metro to get anywhere in paris and 5 minute walk to anywhere in Montmarte.
