We've stayed at the Vanderbilt Condado several times. Pricey but fabulous. This last May we actually stayed two nights there before flying to EIS. I've also heard great reviews for El Convento and the Sheraton both in Old Town to add to mentions by Jason and MIDiver above. Sadly, it sounds like future trips down will be thru STT as the air service from PR to EIS seems to be going thru some rough times.
