Sibiu’s airport is very close to the city centre, closer than in any other Romanian city. Bus No. 11 (which runs until around 23:15) will get you to the city centre (Piata Unirii) in about 15 minutes. Tickets cost 1.50 lei and can be bought from the kiosk or vending machine next to the stop. A taxi should cost no more than 25 lei. Make sure you pick a taxi with the number 942 or 953 on the side.
