9.6/10 Exceptional! (1,629 reviews)
"I thought the hotel had a lot of offer and everything was perfect except for the pillows. Only two per king bed and they are not the best to say the least. Very flat with very little cushion. I'd say bring your own otherwise you may wake up with a sore neck like I did."
