I've not stayed there, but Olga's Fancy looks wonderful to me. Only problem is there appear to be a lot of stairs..

We've stayed at Ronnie's Crystal Palace and enjoyed it. It does NOT have a pool though and there's no bar either.

We've not stayed at Mafolie, but have had drinks there and the view is amazing! There is a bar and restaurant there, but not much to walk to from there though.
