The house is very neat and the neighborhood is quiet, we enjoyed our stay there, it felt like home. Very close to the French Quarter (by car o by cable car) and to a Whole Foods supermarket.
There are neighbors above but we barely heard them.
The AC when ON was making a lot or noise outside the main bedroom window (ours and the neigbors above’s one) and it disturbed our sleep. I don’t think anything can be done against it unfortunately.
