5/5 Excellent
"The entire hotel was fantastic. Beautifully decorated, so much to see. The art gallery was fantastic, the servers at the bar were friendly and phenomenal and just made for a great evening. The food was fantastic. Every inch of the building was well styled and the room was fantastic. Can’t wait to go back! Highly recommend. "
