    8.8/10 - Excellent (690 reviews)
    "Very much enjoyed the property, though they were just starting a remodel/renovation of the lobby, which made it not so inviting for the next week or two. Staff very cordial and helpful. Breakfast fine, room comfy. There was a slight problem with the sealing at the base of the shower, resulting in a little leaking. I would definitely stay there again!"
