Unfortunately, with any beach resort, the proprietors will always be fighting that damp, mustiness that is inherent when you're so close to the sea. However, in my 3 visits last year and my current visit, I haven't seen or smelled anything musty or mildewy.
As far as the decor, I think the whole idea was to create something of a weathered look to make the resort feel as if it has been here since the early 20th century. So yes, the dresser/tv stand, storage bench, headboards and floor lamp have dings and scrapes in their paint or stain finishes. The colors in some of the artwork can seem faded to some people. But the soft goods (bedspreads/bedskirts, carpets and drapes are newer and in good condition, IMO.
Bear in mind that my observations are based on Inn Rooms, so things may be different in the outer villas and beach cottages.
