This has been suggested before for a permanent station "on" Venus, floating in its atmosphere. The atmosphere is caustic, but that's just a design material issue. By maintaining a positive pressure, small punctures would just be a loss to O2 supplies; crew wouldn't need any special safety equipment to patch the holes. Energy could be obtained via solar, chemical engines, or both. Temperature could be controlled by hovering at a spot near the day/night horizon; since the day sid is too hot and the night side too cold, there exists a Goldilocks region. Venus is generally closer than Mars, with a weak magnetic field that would help reduce radiation (along with the atmosphere).
