Excellent location. 30 minutes walking to most major attractions. Parking is not great but there are plenty of places to park for a price. The location itself is very clean and the staff is very helpful. Small messages asking how your day is going is a nice touch. Hands down the best feature is its central location to major events and tourist spots. I would highly recommend it just for its central location.
