I second crested geckos, they are by far the easiest reptiles to care for. As long as you feed them Crested Gecko Diet by Repashy (or a similar complete diet) they are very hardy. They need a good amount of humidity but thus can be achieved by misting in the morning and night. They also thrive at room temperature, just make sure they don't get too hot (above 80 can kill them). They are also really docile!
