Some people have apparently seen the satellites of Jupiter, which is much further away.

All of the Galilean moons would be visible to the naked eye if Jupiter were not so close; Ganymede is mag 4.5 for example. The Venusian Luna would be much brighter, because it is closer to the Sun and closer to us. The separation between Jupiter and Ganymede is 5 arc minutes, while the maximum separation between Venus and Venus-Luna when the planet is brightest (at a distance of around 80 million km) would be 16 arc minutes, so it should be visible quite easily, although not all the time.
