I think the sofa/chair beds at BLT and AKV are a little nicer than some of the other villas. One night last month I decided to sit next to my son on the sofa bed at BLT, and I was quite pleasantly surprised. It was firm, no bars, and quite comfy (I actually dozed off for an hour or so.) I like my king bed in the master, but I gotta say - I could sleep on that particular sofa bed with no issues.
The sofa beds at BWV are still nicer than your average sofa bed (and have a really unique method for set up where all the cushions don't have to be removed.) But once the bed is opened, I don't believe they are quite as nice as the ones at BLT/AKV (but to be honest, I didn't actually test the one at BWV.)
