The best. Possibly the best upscale hotel experience in the past few years, best staff, best breakfast, excellent lower tier restaurant Aqua even during low season (their Michelin1* Es Fum restaurant has been closed till March).
Caveat #1: St, Regis has a wonderful scenic location on the bay, but has no direct access to the sea. Great area for jogging by the bay, even in February. Hotel will advise re beaches.
Caveat #2: no golf on premises (hotel will arrange nearby courses, my woman friend liked Muntaner (with related Quinto second) and Bendinat the best. Other courses nearby tend to be flat (friend sez boring) but I have not seen two lines of 100€-plus automobiles ever like the one at Golf Santa Ponsa - the course being flat and boring according to my experienced golfer friend.
In sum, Marriott St. Regis rules...
