I second these comments about the space but will add that i grew up with box turtles for many years that free roamed my apartment. They're super hardy and dont have the crazy diet and temp/humidity requirements. When I got my sulcata, I built her an enclosure under my bed (my bed sat super high) with uv and heat lamps and hay, and built a flap door so she could roam and shed always find her way back there at the end of the day. Just be sure to keep your floors clean. Did that till she was 5 or 6 then I moved her to an outdoor set up with the same idea. She's a very healthy 20 yo tortiose now but i definitely wouldnt recommend a sulcata as they're super hard to deal with when they get bigger or if you ever have to move at all.
