8/10 Good
"The suite had plenty of room with the separate living area. The sofa bed mattress was not comfortable at all. The bathroom was large with double sinks but had the mirror placed in between the sinks which didn't make sense at all. Other than that we liked the room and it was great for the weekend. The restaurant food was really good also."
