8.6/10 Excellent! (1,009 reviews)
"Staff were helpful and attentive, especially the front desk staff. The hotel is in nice and safe area. The only downside was that the room facing freeway can be noisy at times. However, front desk staff were attentive and accommodating and kindly moved us to a room that didn't face freeway."
