Pia,
Welcome. I wish you were in the US. It would be easy to send you some. The key is to not overwater it. They like to be on the dry side during the winter months. When it warms up, you can increase the watering. They like fast draining soil like cactus mix or orchid mix and then add prelite and some gravel to give it ballast to hold itself down.
What you got looks good so far. They don't need a lot of sun just bright light would do.
The plant you got looks like Sansevieria trifasciata Laurentii. They could grow to 48" tall. Below some of mine. They are Furtua Mix
