free range is the best option for indoor bunnies. think of them like cats. they litter box train and cuddle and act like they own the place. bunny-proofing includes covering up wires so they can't be chewed, making sure shoes and other belongings are off the floor, and table legs, chairs, wall corners, anything that sticks out and is made of wood is protected from bunny teeth. A bunny can absolutely just go loose in your room as long as the above bunny-proofing is doneIf free range isn't an option you can get something called an ex-pen. it's used for puppies a lot of the time but it's perfect for rabbits as long as its fairly large. They need room to exercise, plenty of toys, and unlimited water and hay. rabbits should not drink out of small pet water bottles. they can have the two bowl set up just like any cat or dog for their food and water. food consists of leafy greens, a small amount of pellets, and unlimited timothy hay (alfalfa for baby bunnies) bunnies love to poop while they eat too so it's a good idea to put the food near or inside the litterbox to help with potty training. There is a youtube account that I watch a lot of for bunny advice called "Lennon the Bunny". it's soooooo helpful and I highly recommend checking it out!
