Of the five concierge villas, I believe three are savanna view and two are pool view. But the savanna views from the club level aren't very good because the roof hangs down and blocks part of your view.
Do you mean AKL Concierge or AKV Concierge? If you mean AKL concierge, those are all on the fourth floor and are all savanna view. It you mean AKV concierge, they are what others have already mentioned.
Since you can't seem to find the answers you need via search on the boards. Perhaps this DVC book from PassPorter will answer most of your questions about the basics of DVC ownership.
No, they don't. Washers anddryers are in 1 bedroom, 2 bedroom and grand villa units. There is a DVC laundry room on the 5th floor for those in studios and the washers & dryers are free. You will need your room key to access this laundry room.
