I had to do a powerpoint for school about the secret annex and the people that hid in it. Do you think this is good? I need it to be because it's worth an exam grade. Please give me your feedback and tell me anything I should add or fix.. thanks :]

1. The hideout of the Frank’s, van Pels’ and Pfeffer during the Holocaust.

2.  This level was part of the business.  This level was also part of the business, but the members of the annex often used it during non-business hours.  This level was used by the Frank’s and Pfeffer as a bedroom. The bathroom was also on this level.  This level was used as the van Pels’ bedroom, kitchen, and dining area.  The attic was mainly used for storage.
