How difficult are Rainbow Boas to care for?

Ever since I got my ball python I’ve gotten serious snake fever and I’m super curious about Rainbow Boas! I’m curious to hear from anyone who has/had them what it’s like to care for them? How big of an enclosure? How different are the necessary temps compared to BPs? They seem like a step above taking care of BPs but it’s hard to tell with how iffy online care guides can be.
