About Oitavos Dunes, it is probably the best layout in Portugal at the time. I know that doesn't mean much, but the property is magnificent and the course has some very good holes - probably not a Top 100, but still a place worth playing. It has recently hosted the Portugal Open (I think for the last four years) which probably has helped gained prominence. The clubhouse and food are also fantastic.
In Southern European fashion, they are now screwing it all up by building a hotel between the 1st and 18th holes, and they have also removed all the scrub from the dunes, they looked quite artificial the last time I was there - which is a shame.
