Well it's a motel. But, I was expecting a little more. Pros: 1. Convenience- we were going to the Pomona area, so it is very easy accessible. There are lots of Asian food fusions around. 2. Accessible from freeway, and very easily to find. Cons: 1. we have the Freeway side, so our first night was full of freeway and constructions sound. 2. Bathroom ventilation was super loud. 3. The room itself was clean, however, the sheets and the bedding looked dated and needed to add bleach. 4. Parking lot was sure very dirty. 2. The bathroom

The room smelt like dirty feet. The bedding had a funky odor. The cleanliness could have been waaay better. It was super loud and lots of movement heard from adjoining rooms. Huge crack underneath door.
