8.4/10 Very Good! (2,466 reviews)
"Overall okay stay! staff was super friendly and helpful! Very convenient location. I felt like the room could be more up to date and some parts of the room were dusty. The bed was super comfortable and the sheets were clean. I am a Expedia VIP so I got a voucher for food so that was nice"
