I know some people with single cockatiels that seem to do well, and he will be out a lot, almost all the time when I'm at home. Not for the first month of course, because I am going to take it very slow with introducing them...I talked to a bird behavioralist and the owner of a local reputable bird store, and they think the cockatiel and female parrotlet will be ok as housemates, if I'm careful when I introduce them, and they don't dislike each other for some individual reason (which is always possible...).
My studio apartment is turning into one big bird room. I have a window seat which is becoming the central birdie play area, with a boing and soon some wood perches hanging from the ceiling.
