Hello AndreaB, it looks like Faucaria tuberculosa. In my area it blooms during Fall. Lovely yellow daisy-like flowers.
I just grow them in gritty, well draining media, in containers that are wide, not too deep. They tend to sprawl. I don't water it too often, prefers to be on the dry side, but when I do water, I make sure I water the soil very well, water draining out. They like full sun here, but it is more like part sun due to the canopy of our city trees here by mid afternoon.
Here is mine when it was in bloom last Fall:
If it gets too cold, it may get cold stressed, gets quite colorful but it may get too soft and mushy, so be very careful, if possible keep it dry. I leave mine outdoors year round, so it gets rained on in winter, but I have made the media as gritty as I can, so it survives. I try to position the container backed against our low adobe fence, to reflect heat back to it and to maximize all the sun/heat it can get during winter.
