I like Dachshunds, I really do, but they would be about LAST on my list for apartment dogs. Every one I have every met was LOUD. And most I have met are scared of people out in public and reactive. BARKBARKBARKBARKBARKBARKBARKBARK!! I honestly don't even try to approach most of them at work anymore, they just scream at people who they see walking around the store. Granted, these are almost all from BYB, but that is also probably what you are going to pick up from a shelter.
So make sure you get to spend a bunch of time with one before you bring it home, or at least be able to take it home as a trial. I don't think I've met one yet that would be suitable for an apartment. I think chi/chi mix would be easier to find what you are looking for.
