It is normal to share a flat among young people when they have to study in other countries. This new experience could have its good and bad points.
On the one hand sharing a flat is cheap since you share costs with your flatmates, by the way with a good organisation and sharing the housework can create a good atmosphere of living. If you share a flat you have to put rules in order to have a good relationship with your flatmates and these rules have to be complied with and respected.
On the other hand it can be a problem if flatmates do not respect one another and every person does what they want. Normally, there is often someone who spends a lot more than the others and others that don’t do any housework.
To sum up sharing a flat could be a good experience provided that there is respect between and when each person complies with his obligations or on the contrary it could result in chaos.
