We had a great stay at the apartment and in Paris. The location of it is really good and everything was as expected. Downsides were the 5th floor, which we knew from the other evaluations, so also as expected, but if you have heavy luggage it's still quite the workout :D
Another downside (for us and only for one night) was that the windows were open in the apartment beneath ours, which meant that the windows made a huge noise everytime due to the wind closing them. It was hard to sleep unfortunately due to it. Not the fault from this apartment and we of course don't know if it happens more often, but in case it does it's of course a bigger downside. Considering all of this we still recommend the place.
