I had a look ad other adverts in the Geneva region.
First of all most of them are good. This makes sticking out of the crowd, in a positive way, a challenging task. It even makes it challenging that your advert is at least a bit over average.
Think about adding the french terms to the floor plans.
Regarding the photos. In general they are good, so it is mostly nitpicking.
Switch on all lights. Turn up the blinds.
Adapt the exposure setting such that the room is bright (applies specially to living room)
Have the cushions neatly lined up.
Try to play and find the best view point. Eye level, a bit above, a bit bellow.
Try to get as much of a room as possible. Instead from the door try to stand in an opposite corner (remove furniture as needed)
Look that the corner of the room is a straight vertical line.
Try to have part of the ceiling in the shot (But floor is more important).
Maybe use the poor's man wide angle: Panorama (be careful as thing can get ugly distorted).
Declutter bathroom, specially remove the baby bath (all other pictures are good in this regard).
Close the lid of the loo and the spin dryer.
If there are spurious only partially visible things, remove them (such as the chair in the kitchen, the yellow thingy in the bedroom).
The two crabs and the octopus? I do not know. The first time I was thinking what? Now, I kind of like them.
On anibis, which has most images, one room is missing.
Remember. Nobody can see what a mess is behind your back.
Description (Note, my understanding of French is limited, did you check with a french speaking friend if all is o.k.? )
In the first sentence I would add size and number of rooms. The first two sentences are the most important ones as they are shown in the search overview. The description on Tutti lacks paragraphs. The description on anibis and glocals are good. I like the Layout heading and the tally up of the charges on glocals. Maybe add that it is not a ground floor apartment.
If the rent is high you might have to think about sweetening the deal. Like a half or full month of free rent (think about what an agent would charge).
