Very convenient location for visiting Paris. Agnes was very responsive. We ran into no problems and enjoyed our stay in Paris. As Agnès pointed out, the flat is on the 4th level through very narrow stairs as this is an older building (which is part of its charm!)
The lock gets a little stiff in hot weather. Again part of the charm of the older door mechanism but might be an issue for folks with delicate hands. If you want a taste of living like a Parisian, this is a great place for you!
