Review for Grand Sierra Resort and Casino (GSR) Review For Grand Sierra Resort and Casino (GSR) Google User Jun 4 '17 at 18:07 Always great staff and plenty to do. Rooms are comfy and spacious. They seem to be updating floors one at a time, so the few minor things I could mention may be because of this. I have been staying here off and on for many years and love this location!
