1 minute from Praça tiredentes, about 15 minutes from bus station, location could hardly be better. No Uber so at mercy of local taxi drivers who charge 20 reais to go anywhere in town. In one day, we visited Minas de Passagem by bus, the minerals museum and 3 churches at a leisurely pace. Good food choices near the hotel. Steep streets are hard work - we walked down to Pilar church but caught a bus back up to Tiradentes Square and the sao Francisco Church. The steep streets are cobblestones and hard work going up or down for people, cars and buses. Our bus broke down but nobody was stressed - just waited patiently for the next bus in about 15 minutes.
Really loved Ouro Preto - a world heritage site very well preserved. Our hotel was probably at least 200 years old, so the en-suite bathroom was cramped, but OK.
