Anyone raise a gold in an apartment?

Hello me and gf are moving in together next month and have always wanted a puppy. Not getting one right away but we wanna get one within 3-4 months. What are some challenges within apartments?

-We are moving into a pet friendly apartment

-only have a neighbor on one wall next to us

-we got a first floor apartment so we don’t both people below us.

1. Activity and movement won’t be an issue trust me I will get this puppy moving haha.

I guess my questions are what are the challenges within apartments or stuff we should look out for or consider?
