Let me start by saying that the San Luis has some wonderful people working at this beautiful property. It is a sister property to the Golden Nugget in Vegas. Everyone we came in contact with at the hotel was very friendly and outgoing.
Now for the major negative. Sleep was virtually impossible every night in the room due to the noise coming from slamming doors and yelling people. I realize that it was Spring Break week, the hotel staff seemed unable to control the environment from those wishing to get some sleep. The culmination was our last night there (March 15) when we were unable to go to bed until 3 a.m. Te noise was unlike any I have heard in a hotel and numerous calls to the front desk (by those in many rooms) did nothing to quiet the noise. To his credit, the front desk manager did credit us with $150 the next morning off the room rate. However, because of all the things that you must agree to and check on your check in papers (don't remove your pool wrist band, no towels on the railings of balconies, no lost towel cards, etc) it would seem the San Luis could also require civilized behavior.
One other negative was the "express facial" in the spa. The facial lasted 12 minutes for my wife and not the promised 30 minutes. It consisted of nothing more than washing her face and applying cream. The massages we both received were great.
