Everything.

paying $30 for parking a night was a little excessive.

Amazing

10.0

Jade at the front desk delivered truly outstanding customer service. From the moment I arrived, she greeted me with a warm smile, genuine kindness, and exceptional professionalism. She was friendly, efficient, and went above and beyond to make me feel welcome. Jade's positive attitude and contagious energy set the perfect tone for my entire stay, making my experience even more enjoyable. She is an incredible asset to the hotel, and management should be proud to have someone of her caliber on the team. Her exceptional service deserves to be recognized and celebrated.

Overall good, I should have just told them about it being a queen I was a little uncomfortable.

7.0

Everyone was helpful and it was quiet and clean and pretty on a good side of town.

They put us in a queen when I paid for a king and the WiFi didn’t work.
