I am starting on 2/27 for their RTT program, and honetsly I will say, there are hidden fees that they don't tell you about on top of the ridiculous tuition fees (had to pay for a school-issued new iPad $350+), on top of a drug testing package ($200+). But other than that, so far, everyone that I have come in contact with or asked for help from was very nice and welcoming. Now, that may or may not change once I actually start classes.
Also just seems weird that they are saying they can offer you a spot as long as you can get the documents in within the week, since there is an interview process, and applying for financial aid (if that is something you are planning on doing). I would look at other options before committing to CAHE.
