Some apartment buildings have individual entrances, some are shared by many people. This is a big adjustment if you have never lived in an apartment.
It takes time to get used to the fact that you are essentially sharing some areas of your house with 100 people with different lifestyles! While at first it can be exciting to meet many new people, you have to consider that you will see these people many times over the next year.
You may meet some people that you form a bond with, but you also might meet some people that you just cant warm up to. It is important to remember that all residents have a right to peace, and the quiet enjoyment of their apartment.
