The place of Alexandre and Olivia is located in a very nice area. They managed to allow us to come earlier to the flat and Olivia even asked us if everything was fine during our stay. If the flat is pretty much the same as on the picture, everything was overall fine excepting for the cleaning (bed sheets not very cleaned, scrubs of croissant on the table when we arrived, coffee dosettes full on the machine, lot of dust (my girlfriend is quite allergic to them to she immediately detected them), even if products were provided soap for instance was completely empty and not refilled, etc).
A little bit more effort about that aspect might definitely improve the quality of the stay of the guests and justify the price of the night.
