Staff was very welcoming and friendly. The rooms need updating. The sofa and chair in our room were both stained and dingy. Shower head and fixtures need cleaning. Odor in the lobby faintly smells of sewage or something.

Stephanous was positively incredible. He made sure that everything flowed very smoothly from excellent food service to even going out of his ways to providing an umbrella during a short rain shower. He is a man who understands guest service intrinsically He made a real positive difference in our stay Thank you to Anna and Christous Zavie Montreal Canada
