Great amenities, to find the parking is a little confusing but the space is beautiful. Complimentary water, the food there is on the cheaper side. My only issue was the cleanliness, there was hair and dirt on the floor in and in the shower so it clearly wasnt cleaned the best on the inside.

Clean room and polite staff. Nice lobby, continental breakfast was a nice touch. I found parking is a bit pricey per night, shouldn't charge a guest full price if you're checking after 6 pm on the first night. I would stay here again if I am back in the area
