Just back for 5 nights at the Marbella Club. As mentioned previously no Ocean Views from any room, but we got a wonderful upgrade from a deluxe room to a junior suite. Bathrooms were enormous and had toiletries that my wife enjoyed - but I can't remember.

Breakfast was ample if a bit pedestrian. Didn't dine onsite for any other meals, though we did do a lovely tasting menu at Dani Garcia in the Puente Romano a short walk from the Marbella Club.

We did have a night in their Champagne Bar - which is a wonderful throwback to the early 80's in decor. It was quite empty the night we went (it's still quite low season there) but the champagne selection was excellent and not outrageously priced.

Service was substantially above average - except for housekeeping which was a little hit and miss. It was just warm enough to hang out around the heated salt-water pool at the beach club. Both pool lounger and beverage service was excellent.

The concierge in particular was excellent - both on dining recommendations (at all price/service points) as well as arranging outings and shopping experiences.

The Spa was quite good as well. If you book through Virtuoso, a 40 minute hydrotherapy session is included - quite enjoyable as were the massages.

Another perk of the Virtuoso booking is a free round of golf everyday including transfers to and from - which unfortunately I did not take advantage of, as we were traveling with my parents.
If you'd like any more specifics, feel free to PM.
