Adelaide is super communicative and accommodating. I had accidentally booked the room for a day later than we arrived and she went out of her way to make sure we had a place to stay. Great location for a visit to Paris and very close to the metro.
I found the key very confusing to use and had difficulty understanding the instructions on how to open the door but that was more to do with my knowledge of French I believe. The unit is on the 5th floor (6th if you are from the US) so make sure you are prepared for a good workout! All in all, a great place to crash and filled with personality.
