This hotel sits right next to a very busy freeway. I know the area so I paid extra to get a room on the other side of the freeway. Nice big room. Breakfast was minimal. Pool is nice. Good location for visiting areas in So Calif

The light in the entryway flashed, the lamp next to the couch didn’t work and the body wash bottle was empty. The breakfast buffet had a very limited offerings and there was no meat protein offered.
