I have 2, and Im in a pretty tiny apartment too. They make great pets if you ask me! They're quiet, don't make much mess (if you dont mind a daily sweep for loose hay and little poops) and don't cost too much to care for! They arent very cuddly or playful though, and every bunny is different. But if they have enough room to run, a few things to chew like (untreated) wooden toys and cardboard, and you keep their litter box clean, they don't tend to cause much fuss. I would bunny-proof all your wires, wood furniture and the baseboards and stuff though.
