Everything depends on how you are staying at BCV. Are you in a studio or one/two bedroom? Studio has a double sized sleeper sofa. One or two bedroom has a queen sized in the living room. The second bedroom may have a sleeper sofa and it would be double sized.
Are you staying on points or on cash through CRO? If points, the sleeper sofa will only close up if you close it up. For stays of 7 nights or fewer, you will get your trash removed and towels replaced on day 4. If you are staying 8 nights or more, you will get a full cleaning on day 4 (they will change out the sleeper sofa, but may leave it open) and trash removed and towels replaced on day 8. If you paid cash to CRO, you will get a daily full cleaning, but they usually don't change the sheets but every three or four days. They may leave the sleeper sofa made up, but left open.
The pillows and blanket are stored in the bed on the first night (so look for them as you open up the bed).
