Parking was great. but the gate was locked at 4am in the morning when I first got there. I had called customer service. They lady on the phone sounded very low and she told me the front desk staff could help with the gate. My husband went to the front desk, while I waited at the gate, and the lady was useless. She did not know anything about the garage and told us to ask the Marriott staff to help us. We were able to get in the garage after 30 minutes of trying to access the garage. But the day shift, the gentlemen were very helpful and answered questions and helped us during our stay. We would definitely rent from this place again. Although, the bathroom shower knob are loose, and the shower door is loose.
