The thing to remember about living with snakes in an apartment- even if the landlord allows it- is to be considerate of the fact that MANY people fear snakes. It's NO fun having your neighbors complaining about your pet- not to mention they'll probably shun or hassle you as well- so never walk around outside your apartment holding your snake- keep them concealed in a carrier of some kind. People don't complain about what they're unaware of- so don't make waves.
And if you're trying to convince a landlord to rent to you, it might help to actually show them that this is what you'll do, so they know they won't end up with neighbors complaining or threatening to move out. Landlords really just want good tenants that pay rent, don't damage the building & don't upset the other good tenants. So when you meet a potential landlord, remember they're sizing you up for maturity & trustworthiness- you can make a big difference in how it turns out. And don't blame landlords- they get burned by tenants all the time. Try to understand how they see you & potential pets.
