The location is beyond compare: a Beautiful view of Sacre-Coeur and close to restaurants, shops, and several Metro stations. The apartment was as described with room to sit, work, sleep, and eat the wonderful foods that we bought for breakfast.
The only problem was the state of the bathroom: It was fine for size, hot water, etc. but the drain in the sink did not work. We saw that the sink was very scummy when we arrived (to drop off luggage prior to the cleaners arriving) and realized at night that it looked like that because it didn't drain. I don't know if the cleaners didn't let him know about this problem (which would have been evident when they were cleaning the bathroom) or if he didn't think it was as big a problem as it was. He suggested a way to clean the drain out and then, when that didn't work, to get a drain cleaner at a local store (which did work). I don't recall anything of this sort in any review so I imagine it won't be ongoing.
Again: the location and space are terrific!
